Answers:
gets steepergets less steepnegative========================================
Explanations:
We have m = 1 change to m = 3. As we get further away from 0, the slope gets steeper.Now we're going from m = -6 to m = -1, and we're getting closer to zero. So we're going in the opposite direction as problem 1. Therefore, the line is getting more shallow or less steep.Negative values of m correspond directly to negative slopes, and vice versa. This is simply because m is the slope. Negative slopes visually show a line that goes downhill when you move to the right.Answer:
1: gets steeper
2: gets less steep
3: negative
Step-by-step explanation:
"As the value of m changes from 1 to 3, the graph gets steeper."
m is the slope of the line, and when it increases, there's more "rising" then "running", so it becomes more steep.
"As the value of m changes from -6 to -1, the graph gets less steep."
When the value of m increases, it gets more steep. It makes sense since -6 is less than -1. However, in this scenario, the negative sign doesn't "affect" the slope of the graph. It just flips the graph over the y-axis.
So you have to think of it as if the negative signs were gone and it was 6 to 1.
In that case, the slope is decreasing, so it's getting less steeper.
"If the value of m is negative, the slope of the line is negative."
The m variable represents the slope in slope-intercept form, so if m is negative, that's the same as saying the slope is negative.

Based on the information from both charts, which other country does Russia compare most closely to? Brazil Mexico Japan Uganda
Answer: C-Japan
Step-by-step explanation:
on edge
Russia compares most closely to Brazil, except in Population growth rate, where it scored negative with Japan.
What is the growth rate?Growth rates refer to the percentage change of a specific variable within a specific time period.
Russia has a negative population growth rate of 0.02% and Japan's -0.10%. It has a Fertility Rate of 1.61% comparable to Japan's 1.39%, though its fertility rate of 1.39% and life expectancy of 70 years are most closely matched to Brazil's 1.8% and 73 years respectively. However, you can more closely match Russia to Brazil in two indexes.Demographic information contains the statistics about countries' populations, especially with reference to size, density, distribution, and vital statistics (births, marriages, deaths, life expectancy, fertility rate, etc.).Hence, Russia compares most closely to Brazil, except in Population growth rate, where it scored negative with Japan.

f76r87fgvbhdty
The domain of the function y=2.√(x-6) is all real numbers greater than or equal to 6.
What is a domain?The domain of the function is defined as the set of all the possible values of the function.
The square root function can only take non-negative values, so the expression inside the square root must be greater than or equal to zero:
x - 6 ≥ 0
To calculate the domain of a function, you need to determine the set of all possible input values (also known as the independent variable) that the function can accept and produce a valid output value (also known as the dependent variable). Here are the general steps to find the domain of a function:
Solving for x, we get:
x ≥ 6
Therefore, the domain of the function y=2.√(x-6) is all real numbers greater than or equal to 6. In interval notation, we can write the domain as [6, ∞).

What is the equation of the line of best fit for the following data? Round the
slope and y-intercept of the line to three decimal places.
Answer:
Step-by-step explanation:
I am going to assume that you are doing this on your calculator using the stat button as opposed to having to find it by hand which is so extremely long and drawn out, you'd be dead by the time we found the equation...
The equation of the line of best fit is
y = 1.383x - 1.526
I would explain to you how to do that, but it's a very involved process on your calculator. Find out how to do it and it's the easiest thing in the world!!!
The required equation of the line is y = 0.667x + 2.334
From the table given equation of the line is determined.
x = 4 7 10 12 13
y = 5 7 12 14 18
A line is a curve showing the shortest distance between 2 points.
Standard equation of line, y =mx + c
The slope of equation m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] and c is y intercept.
m = 7-5/7-4
m = 2/3
Now put m in the standard equation
y = 2x/3 + c - - - - -(1)
to find the value of c we will put a point (7, 7) in the equation.
7 = 7*2/3 + c
c = 7 - 14/3
c = (21-14)/3
c = 7/3
Put c in equation 1
y = 2x/3 + 7/3
y = 0.667 x +2.334
Thus, The required equation of the line is y = 0.667 x +2.334

Please explain how u did it… thanks! <3
Answer:
(1, 2 )
Step-by-step explanation:
Given the 2 equations
- 2x - y = - 4 → (1)
x + 2y = 5 → (2)
Multiplying (2) by 2 and adding result to (1) will eliminate x- term
2x + 4y = 10 → (3)
Add (1) and (3) term by term to eliminate x
0 + 3y = 6
3y = 6 ( divide both sides by 3 )
y = 2
Substitute y = 2 into either of the 2 equations and solve for x
Substituting into (2)
x + 2(2) = 5
x + 4 = 5 ( subtract 4 from both sides )
x = 1
solution is (1, 2 )

Step-by-step explanation:
a parabola is symmetric (has a mirror image)
a parabola has ONE vertex (a highest or lowest point).
thus a line that goes through the vertex is it's axis of symmetry.
x = 5 , x=99, x=102 are vertical lines that intersect the x axis no matter what the y value is....
your axis of symmetry is a line that looks like X= SOMETHING
the "something" is the X value of the vertex, which is (-2,3)

How will the solution of the system y > 2x + 2/3 and y <
2x + 1/3 change if the inequality sign on both inequalities
is reversed to y < 2x + 2/3 and
y> 2x + 1/3?
Answer:
The solution will go from NO common solutions to infinite solutions between the 2 parallel lines.
Step-by-step explanation:
In the original case all solutions for equation 1 are above line 1 (y >) and all solutions for equation 2 are below line 2 (y <), so there is no overlap and therefore no common solutions. When reversed, all solutions for line 1 are below line 1 and all solutions for line 2 are above line 2. So the overlap is everything between the two lines.
Answer:
The shaded area would reverse on both inequalities.
The graphs do not overlap until the signs are reversed.
There are an infinite number of solutions in the system once the signs are reversed.
There are no solutions before they are reversed.

Additional comment
You will notice this is the same formula as is used for a rectangle. You can consider the parallelogram to have the same area as a rectangle of these dimensions if you look at what happens when you cut the right triangle from the right end and add it to the left end. The result is a rectangle 5 units wide and 4 units high.
The same formula applies even if the skew is so great that the bases do not overlap. (That much skew would not result in a triangle of the kind shown in this diagram.)

A freight train leaves a station and travels north at 60 mph. 4 hours later, a passenger train leaves on a parallel track and travels north at 100 mph. How long will it take the passenger train to overtake the freight train? How far from the station will they meet?
Answer:
first do:
60mph * 4 hours= 240mi
Let D = the distance the passenger train has to
travel to catch the freight train
Start a stopwatch when the passenger train leaves
Let t = the time on the stopwatch when they meet
Equation for freight train:
d-240=60t
Equation for passenger train:
d=100t
all together:
100t-240=60t
we can do 100t-60t because they both have (t)= 40t
40t=240 *now divide 240 by 40= 6
THEN do:
D= 100mph x 6= 600mi
They will meet 600 mi from the station
to check:
d-240=60t x 6
600-240= 360
60 x 6= 360
360=360
The function g(x) = \frac{1}{2}\left| {x} \right|g(x)= 21 ∣x∣ is a transformation of the absolute value parent function. Which graph shows g(x)?
Answer:
A
Step-by-step explanation:
From what we have , it is expected that the parent function is a v-shaped graph that starts from the origin
The expected equation parent function should be;
y = |x|
Now, moving on, the transformed function is 1/2 of the parent function
This shows a direct compression of the initial partner function
So, it is expected that the transformed function is more compressed compared to the initial parent function
so, the correct choice of answer here is first option

Let R be a relation on the set of all lines in a plane defined by (l 1 , l 2 ) R line l 1 is parallel to l 2 . Show that R is an equivalence relation.
Answer: hello your question is poorly written below is the complete question
Let L be the set of all lines in XY plane and R be the relation in L defined as R = {(L1, L2): L1 is parallel to L2}. Show that R is an equivalence relation. Find the set of all lines related to the line y = 2x + 4.
answer:
a ) R is equivalence
b) y = 2x + C
Step-by-step explanation:
a) Prove that R is an equivalence relation
Every line is seen to be parallel to itself ( i.e. reflexive ) also
L1 is parallel to L2 and L2 is as well parallel to L1 ( i.e. symmetric ) also
If we presume L1 is parallel to L2 and L2 is also parallel to L3 hence we can also conclude that L1 is parallel to L3 as well ( i.e. transitive )
with these conditions we can conclude that ; R is equivalence
b) show the set of all lines related to y = 2x + 4
The set of all line that is related to y = 2x + 4
y = 2x + C
because parallel lines have the same slopes.
Three cyclists simultaneously start their movement from the same point at 7 am. Their routes take 10 minutes, 25 minutes and 15 minutes, respectively. When will be the first time that the three cyclists meet again at the starting point?
Answer:
The 3 cyclists will meet at the starting point again after 150 minutes.
Step-by-step explanation:
Since they start at the same point but then take different times to each route, then to find the first time they will each meet at the starting point, we have to find the lowest common multiple (LCM).
Let's use prime factorization to get it.
Prime factorization of 10 = 2 × 5
Prime factorization of 15 = 3 × 5
Prime factorization of 25 = 5 × 5
Thus,super set = 2, 3, 5, 5
Thus,LCM = 2 × 3 × 5 × 5 = 150
Thus,the 3 cyclists will meet at the starting point again after 150 minutes.
The profitability, P, of a popular restaurant franchise can be modeled by the function P (t) = t4 – 10t3 + 28t2 – 24t, where t is the number of months since the restaurant opened. How many months after the franchise opens will it begin to show a profit?
A. 0 months
B. 2 months
C. 4 months
D. 6 months
In this question, the profit of the restaurant after t months is given by a polynomial function. To find when it begins to show a profit, we find the numerical values of the function for t, and it shows a profit when [tex]t > 0[/tex]
Profit after t months:
[tex]P(t) = t^4 - 10t^3 + 28t^2 - 24t[/tex]
0 months:
This is P(0). So
[tex]P(0) = 0^4 - 10*0^3 + 28*0^2 - 24*0 = 0[/tex]
1 month:
This is P(1). So
[tex]P(1) = 1^4 - 10*1^3 + 28*1^2 - 24*1 = -5[/tex]
2 months:
This is P(2). So
[tex]P(2) = 2^4 - 10*2^3 + 28*2^2 - 24*2 = 0[/tex]
3 months:
This is P(3). So
[tex]P(3) = 3^4 - 10*3^3 + 28*3^2 - 24*3 = -9[/tex]
4 months:
This is P(4). So
[tex]P(4) = 4^4 - 10*4^3 + 28*4^2 - 24*4 = -32[/tex]
5 months:
This is P(5). So
[tex]P(5) = 5^4 - 10*5^3 + 28*5^2 - 24*5 = -45[/tex]
6 months:
This is P(6). So
[tex]P(6) = 6^4 - 10*6^3 + 28*6^2 - 24*6 = 0[/tex]
7 months:
This is `P(7). So
[tex]P(7) = 7^4 - 10*7^3 + 28*7^2 - 24*7 = 175[/tex]
After 7 months it shows profit, so it starts showing profit on the 6th month, and thus, the correct answer is given by option D.
