Answer:
y = -2x
Step-by-step explanation:
Equation in slope-intercept form is y = mx + b.
m = slope = ∆y/∆x
Using any two points on the line, say (0, 0) and (-20, 40),
Slope (m) = (40 - 0) / (-20 - 0) = 40/-20
Slope (m) = -2
b = y-intercept = the value of y when x = 0.
b = 0
To write the equation of the line, substitute m = -2 and b = 0 into y = mx + b
Thus:
y = -2x + 0
y = -2x
Answer:
She has 20 coins in her bank, where she has 12 nickels and 8 quarters
Step-by-step explanation:
- A nickel is 5 cents
- Since she has 8 fewer than nickels, we add 8 to the number of nickels
Q = N + 8, 25Q + 5N = 560
25(N + 8) + 5N = 560
25N + 200 + 5N = 560
25N + 200 - 200 + 5N = 560 - 200
30N = 360
30N / 30 = 360 / 30
N = 12 nickels
Finding amount of Quarters:
Q = N + 8 → Q = 12 + 8
Q = 20 quarters

Answer: OPTION D
Step-by-step explanation:
The formula for calculate the surface area of a rectangular prism is:
Where w is the width, h is the height and l is the length.
You can see in the figure attached that:
l=3.4ft
w=3ft
h=4.1ft
Therefore, when you substitute these values into the formula you obtain that the surface area is:
![SA_{rp}=2[(3ft*4.1ft)+(3.4ft*3ft)+(3.4ft*4.1ft)]=72.88ft^{2}](https://tex.z-dn.net/?f=SA_%7Brp%7D%3D2%5B%283ft%2A4.1ft%29%2B%283.4ft%2A3ft%29%2B%283.4ft%2A4.1ft%29%5D%3D72.88ft%5E%7B2%7D)
