Answer:
I guess we have the table:
x f(x)
-4 7
-2 5
0 3
2 1
4 - 1
To find the slope of this, we need to select two different points (x1, y1) and (x2, y2) and use the relation:
slope = (y2 - y1)/(x2 - x1)
let´s use the first two:
(-4,7) and (-2, 5)
Slope = (5 - 7)/(-2 - (-4)) = -2/2 = -1
Now, if we want to be sure that this is a linear equation, we should do the same for other two pairs of points, now use the first and the third:
(-4, 7) and (0,3)
S = (3 - 7)/(0 -(-4)) = -4/4 = -1
Now, for the function g(x) we can see a constant line, that is parallel to the x-axis.
This means that the slope of this function is equal to zero.
This means that the slope of g(x) is bigger than the slope of f(x), because 0 > 1 i guess

Manuel needs to buy plastic spoons. Brand Ahas a box of 12 spoons for $1.12. Brand B has a box of 25 spoons for 2.69 Find the unit price for each brand. Then state which brand is the better buy based on the unit price. Round your answers to the nearest cent. Unit price for the Brand A spoons: I for each spoon Unit price for the Brand B spoons: $] for each spoon The better buy: O Brand A O Brand B O Neither (They have the same unit price)
Answer:
Brand A: 0.92 Brand B: 0.11
Step-by-step explanation:
1.12 divided by 12 (round down)
2.96 divided by 25 (round up)
brand B is better to buy because you get more and it costs less per spoon

Answer:
Value of x = -7
Step-by-step explanation:
Given:
First angle = 83°
Second angle = 24°
Third angle = (38 - 5x)°
Find:
Value of x
Computation:
We know that sum of all interior angle in triangle is 180°
So,
83 + 24 + 38 - 5x = 180
145 - 5x = 180
-5x = 35
x = -7
Value of x = -7

A VERTICAL line passes through the point (4, 5). Find an equation for this line.
A)
X = 4
B)
y = 5
C)
y = 4
D)
y = 4x + 5
Answer:
A
Step-by-step explanation:
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (4, 5 ) with x- coordinate 4 , then
x = 4 ← equation of vertical line → A
in 1910, halley's comet traveled close to earth about 1/7 of the distance from the earth to the sun. Earth's distance from the sun is 149.6 million kilometers. ( if u answer all them i'll give u brainliest but if not its alr)
1. How close was halley's comet to earth in 1910?create an equation to answer the question.
2. estimate the next 3 years when halley's comet will appear.
3. the core of halley's comet is oblong in shape, with its longest dimension 16 km long. earth's diameter is about 12,700 km . how many times larger in diameter is earth than halley's comet?
1) In 1910, Halley's Comet was 21.37 million kilometers close to Earth.
2) Given that Halley's Comet orbits the sun at about 75 years, and that the last time it passed near the Earth was in 1986, the years in which it will happen again will be 2061, 2136 and 2211.
3) Earth is 794 times larger in diameter than Halley's Comet.
Since in 1910, Halley's Comet traveled close to Earth about 1/7 of the distance from the Earth to the Sun, and Earth's distance from the Sun is 149.6 million kilometers, to determine 1) how close was Halley's Comet to Earth in 1910, 2) estimate the next 3 years when Halley's Comet will appear, and 3) if the core of Halley's Comet is oblong in shape, with its longest dimension 16 km long, and Earth's diameter is about 12,700 km, how many times larger in diameter is Earth than Halley's Comet, the following calculations must be performed:
1)
149.6 / 7 = X 21.37 = X
2)
1986 + 75 = 2061 2061 + 75 = 2136 2136 + 75 = 2211
3)

The relationship between Halley's comet and the earth is an illustration of proportions
The given parameters are:
Earth's distance from the sun = 149.6 million kilometersHalley's comet traveled close to 1/7 of the distance.(a) The distance
The distance which Halley's comet get to is calculated using:
[tex]d = \frac 17 \times 149.6\ million\ km[/tex]
So, we have:
[tex]d = 21.37\ million\ km[/tex]
Hence, Halley's comet was 21.37 million kilometers close to the earth in 1910.
(b) The next three years it will appear
From the complete question, the comet is visible every 74 years.
It appears in 1910.
So, the next three years are:
[tex]Year\ 1 = 1910 + 74 = 1984[/tex]
[tex]Year\ 2 = 1984 + 74 = 2058[/tex]
[tex]Year\ 3 = 2058 + 74 = 2132[/tex]
Hence, the comet will appear in 1984, 2058 and 2132.
(c) The number of times the earth is larger
The diameter of the earth is given as: 12700 km, while the longest dimension of the oblong shaped comet is 16 km.
So, the number of times (n) which the earth is greater than the comet is:
[tex]n = \frac{12700}{16}[/tex]
[tex]n = 794[/tex] --- approximated
Hence, the diameter of the earth is 794 times larger than Halley's Comet.

Which method would be the most efficient way to solve the method : substitution method, Eliminating method or equal value 3x+y=1 4x+y=2
Answer:
Eliminating method
Step-by-step explanation:
For the given situation i.e.
3x + y = 1
And,
4x + y = 2
Here we use the elimination to determine the value of x and y
So,
3x + y = 1
4x + y = 2
- - -
-x = -1
x = 1
Now put the value of x in any of the above equation
So,
3 + y = 1
y = -2

What is the area of this rectangle? A rectangle that is partitioned into two rectangles. The first rectangle has a measurement of five meters along the top, and a measurement of eight meters along the side. The second rectangle has a measurement of five meters along the top, and a measurment of eight meters along the side. 50 square meters 60 square meters 70 square meters 80 square meters
Answer:
80 square meters
Step-by-step explanation:
A rectangle that is partitioned into two rectangles; rectangle A and rectangle B
Rectangle A:
Top = 5 meters
Side = 8 meters
Area of rectangle A = length × width
= 5 meters × 8 meters
= 40 meters ²
Rectangle B:
Top = 5 meters
Side = 8 meters
Area of rectangle B = length × width
= 5 meters × 8 meters
= 40 meters ²
Total area of the partitioned rectangle = area of rectangle A + area of rectangle B
= 40 meters ² + 40 meters ²
= 80 meters ²
