Hello!
Find the coordinate where x = -1:
At x = -1, y = 1, so the coordinate is (-1, 1).
Find the coordinate where x = 2:
At x = 2, y = -2, so the coordinate is (2, -2).
Find the rate of change between the points using the slope formula:
Plug in the coordinates above:
Simplify:
Thus, the rate of change between the points is -1.
Answer:
50
Step-by-step explanation:
Let's say the smaller number is x then
x + x + 2 = 98
2x+2 = 98
2x = 96
x = 48
==> 48, 50
8*8=64 8 *4(sides) is 32 but that's an equilateral triangle
From the given volume, we know that the ratio is:
![\text {Ratio of yellow eraser to white eraser = } \sqrt[3]{ \dfrac{16}{2} }](https://tex.z-dn.net/?f=%5Ctext%20%7BRatio%20of%20yellow%20eraser%20to%20white%20eraser%20%3D%20%7D%20%20%5Csqrt%5B3%5D%7B%20%5Cdfrac%7B16%7D%7B2%7D%20%7D%20)
From the given area, we know that the ratio is:
Equate the two ratio and solve for x:
![\sqrt[3]{ \dfrac{16}{2} } = \sqrt{ \dfrac{52}{x} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%20%5Cdfrac%7B16%7D%7B2%7D%20%7D%20%20%3D%20%5Csqrt%7B%20%5Cdfrac%7B52%7D%7Bx%7D%20%7D%20)
Cube both sides:
Square both sides:
Simplify each term:
Cross multiply:
Divide both sides by 256:
Cube root both sides:
Answer:
$588 was left
Step-by-step explanation:
- Since it was $40 for 3.5 years, and there are 12 months in a year, we do: (3*12+6)*40=1680
- 65%= 13/20
- 13/20 * 1680
- Sam paid $1092
- 1680 - 1092 = 588
