Answer: (a)
Step-by-step explanation:
Given
The given graph is y=-2x+6 and it changed to y=3x+2
The slope of the graph determines the steepness
Slope changes from -2 to 3. So, latter graph is more steeper.
Also, y intercept is obtained by putting x as 0
Y intercept changes from 6 to 2 i.e. decrease of 4 units
Hence, option (a) is correct.
Person 1 can do a certain job in twenty-one minutes, and person 2 can do the same job in twenty-eight minutes. When
completing the job together, which expression would be used to represent the amount of work done by person 1?
A. 21
B. X/21
C. 21x
D. 1/21
Answer:
C) x/21
Step-by-step explanation:
Since Person 1 can complete the entire job (100% = 1/1 = 1) in 21 minutes, this person can complete 1/21 of the job per minute. This is Person 1's rate. If x is the amount of time it takes both people together to finish the job, then the amount of work Person 1 does would be (1/21)(x) = x/21.
12. If I || m, find the value of x.
(9x - 4)+3 (5x + 16)
I know that X=12
But I need help showing my work
Answer:
x = 12
Step-by-step explanation:
(9x - 4)° + ( 5x + 16 )° = 180°
9x + 5x - 4 + 16 = 180
14x + 12 = 180
14x = 180 - 12
14x = 168
x = 12

Find the common difference of the arithmetic sequence -6, -13, -20,...
Answer:
-7
Step-by-step explanation:
arithmetic sequences are consistant sequences by adding or subtracting a constant term, in this case to get from -6 to -13, you subtract 7. And to get from -13 to -20 you subtract 7 again. The next number in the sequence would be -27 as -20-7= -27
Hope this helps!
The common difference of the arithmetic sequence -6, -13, -20 is -7.
To find the common difference of an arithmetic sequence, we subtract any term from the term that follows it.
In the given sequence -6, -13, -20, the common difference can be found by subtracting each term from the term that follows it as:
-13 - (-6) = -13 + 6 = -7
-20 - (-13) = -20 + 13 = -7
From the calculations above, we can see that the common difference of the arithmetic sequence -6, -13, -20 is -7.

Write the equation in standard form for the circle with center (0, -8) and radius 6.
Answer:
(x)^2 + (y+8)^2 = 36
Step-by-step explanation:
The standard form for an equation for a circle is
(x-h)^2 + (y-k)^2 = r^2 where ( h,k) is center of the circle and r is the radius
(x-0)^2 + (y- -8)^2 = 6^2
(x)^2 + (y+8)^2 = 36

Answer:
x = 2
Step-by-step explanation:
The axis of symmetry is a vertical line passing through the vertex, with equation
x = c ( c is the x- coordinate of the vertex ) , then
x = 2 ← equation of axis of symmetry
Answer:
x=2
Step-by-step explanation:
To find the axis of symmetry for a quadratic, you use the formula:
[tex]x=-2ba[/tex]
Looking at the chart, we can see that [tex]b=-1[/tex] (the vertical shift) and [tex]a=1[/tex] (the slope. Plugging these values into the formula, we get:
[tex]x=-2(-1)(1)=2[/tex]
Therefore, [tex]x=2[/tex] is the axis of symmetry.
The much simpler way of determining this, however, is simply looking at the graph and finding where the vertex is. It is given here that the vertex point is (2, -1) and the graph is mirrored horizontally so you can simply take the x-coordinate and that will be the axis of symmetry. If the parabola was mirrored vertically, the axis of symmetry would then be the y-coordinate of the vertex.
Solve 5x2 = 180 algebraically.
Answer:
x = ±6
Step-by-step explanation:
5x^2 = 180
Divide each side by 5
5x^2/ 5 = 180/5
x^2 = 36
Take the square root of each side
sqrt(x^2) = ± sqrt(36)
x = ±6
Answer: x = 6 or x = -6
Step-by-step explanation: First, isolate the x squared by dividing both sides by 5 to get x² = 36. Now, since x is squared, we simply take the square root of both sides of the equation to get x by itself.
When we take the square root of both sides of an equation,
we must always make sure to use plus or minus!
So x = ±5 and you can write your answer as the solution set {6, -6}.

Answer:
they are NOT similar!
Step-by-step explanation:
the angles are not conguent or they are not the same in words
the don't add up with the same sum of angles,
so your explanation would be:
45 plus 29 has a sum of 74 for the right triangle and the left triangle has angles 106 degrees plus 29 degrees with a sum of 135 degrees, there-fore the triangles aren't similar because the angles are not equal to each other
9514 1404 393
Answer:
∆AFN ~ ∆SHE . . . . AA~
Step-by-step explanation:
The third angle in triangle HSE is ...
180° -45° -29° = 106°
This means two angles in ∆SHE match two angles in ∆AFN. (106° and 29°) The triangles are similar by AA~.
Listing vertices in order of smallest-to-largest angles, the similarity statement is ...
∆AFN ~ ∆SHE . . . . AA~

illustrate the solution of the inequality ( x - 5) ( x + 5)≥ 0. on the number line
Answer: The diagram is shown below
==============================================================
Explanation:
If you graphed y = (x-5)(x+5) on the xy grid, then you'd see a parabola forming. This parabola has x intercepts at -5 and 5. The parabola opens upward.
If x < -5, then (x-5)(x+5) is positive. Let's say x = -6
(x-5)(x+5)
(-6-5)(-6+5)
(-11)(-1)
11
So if x = -6, then y = (x-5)(x+5) becomes 11 which is positive. If you picked any other value less than -5, then (x-5)(x+5) is positive.
Similarly, if x > 5, then (x-5)(x+5) is also positive for similar reasoning. Try x = 6 to see what happens. The actual value itself doesn't matter. All we care about is if the result is positive or negative.
It's only when -5 < x < 5 that (x-5)(x+5) is negative. Consider x = 0 which is between -5 and 5
Plugging x = 0 leads us to
(x-5)(x+5)
(0-5)(0+5)
(-5)(5)
-25
Showing that (x-5)(x+5) is negative on the interval -5 < x < 5
---------------------------------------------
Going back to the original inequality, we want to know when (x-5)(x+5) is positive or 0
We found that (x-5)(x+5) is positive when x < -5 or when x > 5
(x-5)(x+5) is equal to zero when x = -5 or x = 5
So overall, the solution we want is [tex]x \le -5 \ \text{ or } \ x \ge 5[/tex]
To graph this on a number line, we plot closed filled in circles at -5 and 5. Then we shade everything that is not between these two circles (so we shade everything except the interval -5 < x < 5).
The graph is below.
Can u guys hurry up pleasee The manager of a local appliance store wants to conduct a customer satisfaction survey. Which population should the manager survey? A.Sales people in the store. B.People in charge of repairs at the store. C.People who bought a major appliance from the store. D.Prospective buyers who visit the store.
C. People who bought a major appliance from the store.
Step-by-step explanation:A customer satisfaction survey is a market survey carried out to analyze how satisfied users or customers are in using or consuming a particular product or service. Basically, it has to be carried out on the customers themselves. By costumers, we mean those that have bought and/or used the service or product.
For the local appliance store, the manager should survey people that have bought at least one major appliance from the store. Those are the right people that should make up the population to be surveyed. This is because;
i. They are the consumers of the product.
ii. They have bought and definitely used the product.
iii. They have some usable and useful experiences since they have handled the product.
