Answer:
f(-10) = -1/2
f(0) = -3
Step-by-step explanation:
Here, given the equation for f(x) we want to get the value of f(x) for each value of x supplied
We proceed as follows
f(-10) = 6/-10-2 = 6/-12 = -1/2
f(0) = 6/(0-2) = 6/-2 = -3

Find the surface area of the prism.
Answers
Answer and Step-by-step explanation:
To find the surface area, all you have to do is find the area of each face of the prism, and then add them all together.
15 x 20 = 300
(15 x 8)/2 = 60
(15 x 8)/2 = 60
(There are two triangles)
8 x 20 = 160
20 x 17 = 340
Now, add them all together.
300 + 60 + 60 + 160 + 340 = 920
The surface area of the prism is 920 [tex]units^{2}[/tex]

Mr. Green paid $7.50 for a set of dry erase markers. He used a $2.00 coupon for his purchase. Write AND solve an equation that represents the difference between d, the original price of the markers and the coupon. Solve for d.
Answers
Answer:
[tex]d - 2 = 7.50[/tex]
$9.50
Step-by-step explanation:
Given that:
Money paid by Mr. Green for a set of dry erase markers = $7.50
Coupon used for the purchase = $2.00
To find:
The equation and solution to represent the difference the original price [tex]d[/tex] of the markers and the coupon.
Solution:
Given that, the original price of the dry erase markers = $[tex]d[/tex]
Coupon amount = $2.00
Amount paid = $7.50
The equation can be made by subtracting the coupon amount from the original price and comparing it with the amount paid by Mr. Green for the purchase.
Original price = $([tex]d[/tex] - 2)
[tex]d - 2 = 7.50[/tex]
Solving the above equation by adding 2 on both the sides:
[tex]d -2+2= 7.50+2\\\Rightarrow d = \$9.50[/tex]

Answer:
The solution to the system of equation is (1,-4)
Step-by-step explanation:
Here, we want to find the solution to the system of equations
Since we have y in both places, we can equate the two
That would be;
-x-3 = -7x + 3
-x + 7x = 3 + 3
6x = 6
x = 6/6
x = 1
y = -x - 3
y = -1 -3
y = -4
So the solution to the system of equations is (1,-4)

hannah spends 20% of her money on sweets and 32% on fares. if she spent $8 on sweets what is:
(1) the amount of money she originally had?
(2) the amount of money spent on fares?
(3) the amount she has left?
Answers
Answer:
1) $40
2) $12.80
3) $19.20
Step-by-step explanation:
(a) find: 8 is 20% of what number
use proportion: is = percent
of 100
is = 8
of = what you're solving for, let's say 'x'
20% = 20/100
8 = 20
x 100
cross-multiply: 20x = 800
x = 40
(b) money spent on fares: 32% of 40 is what number?
32 = y
100 40
1280 = 100y
y = 12.80
3) 40 - (8.0 + 12.80) = 40 - 20.8 = 19.20

Answer:
[tex]\mathbf{A}= \,\,\left\{(2, 9),\,\,(4, 5),\,\,(6, 1),\,\,(7, -1)\right\}[/tex]
Step-by-step explanation:
Given
Ordered pairs A - D
Required
Which represents a linear function?
To do this, we simply calculate the slope (m) of each ordered pairs.
[tex]m = \frac{y_2 - y_1}{x_2-x_1}[/tex]
Considering A:
[tex]\mathbf{A}= \,\,\left\{(2, 9),\,\,(4, 5),\,\,(6, 1),\,\,(7, -1)\right\}[/tex]
Consider the following pairs
[tex](x_1,y_1) = (2,9)[/tex] and [tex](x_2,y_2) = (4,5)[/tex]
[tex]m = \frac{5 - 9}{4 -2} = \frac{-4}{2} = -2[/tex]
Consider the another pairs
[tex](x_1,y_1) = (2,9)[/tex] and [tex](x_2,y_2) = (6,1)[/tex]
[tex]m = \frac{1 - 9}{6 -2} = \frac{-8}{4} = -2[/tex]
Consider the another pairs
[tex](x_1,y_1) = (2,9)[/tex] and [tex](x_2,y_2) = (7,-1)[/tex]
[tex]m = \frac{-1 - 9}{7 -2} = \frac{-10}{5} = -2[/tex]
The slope is uniform all through.
i.e.
[tex]m = -2[/tex]
Hence, this can be a linear function
Considering B:
[tex]\mathbf{B}= \,\,\left\{(-1, -8),\,\,(0, -3),\,\,(1, 3),\,\,(2, 8)\right\}[/tex]
Consider the following pairs
[tex](x_1,y_1) = (-1,-8)[/tex] and [tex](x_2,y_2) = (0,-3)[/tex]
[tex]m = \frac{-3 - (-8)}{0 - (-1)} = \frac{-3 +8}{0 +1} = \frac{5}{1} = 5[/tex]
Consider the another pairs
[tex](x_1,y_1) = (-1,-8)[/tex] and [tex](x_2,y_2) = (1,3)[/tex]
[tex]m = \frac{3 - (-8)}{1 - (-1)} = \frac{3 +8}{1 +1} = \frac{11}{2} = 5.5[/tex]
The calculated slopes are not equal.
i.e.
[tex]m = 5[/tex] and [tex]m = 5.5[/tex]
Hence, this can't be a linear function
Considering C:
[tex]\mathbf{C}= \,\,\left\{(-9, 5),\,\,(-3, 3),\,\,(3, 0),\,\,(9, -2)\right\}[/tex]
Consider the following pairs
[tex](x_1,y_1) = (-9,5)[/tex] and [tex](x_2,y_2) = (-3,3)[/tex]
[tex]m=\frac{3-5}{-3-(-9)} = \frac{3-5}{-3+9} = \frac{-2}{6} = -\frac{1}{3}[/tex]
Consider the another pairs
[tex](x_1,y_1) = (-9,5)[/tex] and [tex](x_2,y_2) = (3,0)[/tex]
[tex]m=\frac{0-5}{3-(-9)} = \frac{0-5}{3+9} = \frac{-5}{12} = -\frac{5}{12}[/tex]
The calculated slopes are not equal.
i.e.
[tex]m = -\frac{5}{12}[/tex] and [tex]m = -\frac{1}{3}[/tex]
Hence, this can't be a linear function
Considering D:
[tex]\mathbf{D}= \,\,\left\{(1, -8),\,\,(2, -6),\,\,(3, -3),\,\,(4, 0)\right\}[/tex]
Consider the following pairs
[tex](x_1,y_1) = (1,-8)[/tex] and [tex](x_2,y_2) = (2,-6)[/tex]
[tex]m = \frac{-6 - (-8)}{2 - 1} = \frac{6 + 8}{1} = \frac{14}{1} = 14[/tex]
Consider the another pairs
[tex](x_1,y_1) = (1,-8)[/tex] and [tex](x_2,y_2) = (3,-3)[/tex]
[tex]m = \frac{3 - (-8)}{-3 - 1} = \frac{3 + 8}{-4} = \frac{11}{-4} = -\frac{11}{4}[/tex]
The calculated slopes are not equal.
i.e.
[tex]m = -\frac{11}{4}[/tex] and [tex]m = 14[/tex]
Hence, this can't be a linear function
From the calculations above:
Only (A) can be a linear function

Answers
Answer:
c (100)
Step-by-step explanation:
on edg 2021 ^u^
The width of the tower at the top will be 92 m. Then the correct option is B.
What is a hyperbola?The hyperbola is the locus of a point such that the difference of distance from point P to two non-movable points. These two points are called foci of hyperbola.
A cooling tower is 120 meters tall.
The sides of the tower are in the shape of a hyperbola defined by the equation x²/500 – y²/900 = 1 with units in meters.
The center of the tower is at the origin.
Then the width of the tower at the top will be
x²/500 – (120)²/900 = 1
x²/500 – 14400/900 = 1
x²/500 – 16 = 1
x²/500 = 1 + 16
x²/500 = 17
x² = 8500
x = 92.19 ≈ 92 m
Then the correct option is B.

What is the mean of the distribution?
2.5
2.95

3.5
Answers
Answer:
The center for the distribution of scores appears to be higher for subject B than for subject A.
The mean of the distribution when X represent the score on a randomly selected exam so here the mean be like 2.95.
Calculation of the mean:Since
Column 1 is labeled score with entries 1, 2, 3, 4, 5.
Column 2 is labeled probability with entries 0.18, 0.20, 0.26, 0.21, 0.15.
So it be like
= (0.18) (1) + (0.20) (2) + (0.26) (3) + (0.21) (4) + (0.15) (5)
= 0.18 + 0.40 + 0.78 + 0.84 + 0.75
= 2.95
Hence, the third option is correct.

Write the slope-intercept form of the equation of the line through the given points: (-2,13) and (4,1)
Answers
Answer: y = -2x + 9
Step-by-step explanation:
Points through which the line passes through are: (-2,13) and (4,1)
The slop intercept form will be in terms of:
y = mx + c
Find m first which is the slope:
= (Y₂ - Y₁) / (X₂ - X₁)
= (1 - 13) / (4 - (-2))
= -12 / 6
= -2
Using a point on the line and the slope, calculate c which is the y intercept:
Using point (-2,13) :
y = mx + c
13 = -2 * -2 + c
13 = 4 + c
c = 13 - 4
c = 9
Slope intercept form of line is therefore:
y = -2x + 9
