Step-by-step explanation:
The applicable property of exponents is ...
![\sqrt[n]{x^m}=x^{\frac{m}{n}}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%5Em%7D%3Dx%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D)
The 4th selection uses this property directly. The 3rd selection uses the property

to show that the cubes of the two expressions are equivalent. Since all the numbers involved are real numbers, this is equivalent to showing the expressions equivalent.
Answer:
12.5 in by 6 in
Step-by-step explanation:
The dimensions would be 250 / 20 = 12.5 inches by 120 / 20 = 6 inches.
Answer:
y=mx+b
m = slope
b = y-intercept
To find slope we use the equation, change in y divided by the change in x. Let's use points (2, 2) and (3, 1).
(2-1) / (2-3) = -1
Meaning our slope is -1 and it will be going down.
Next, we have to find the y-intercept which is the value of y when x=0. When x is 0 y will be 4.
y=-1x+4
