Answer:
<u>The simplified expression is y raised to the 2/8 power</u>
Step-by-step explanation:
Let's recall that one of the properties of fractional exponents is:
x ^ a/b = ᵇ√x ᵃ
therefore,
⁸√y² = y ^2/8
<u>The simplified expression is y raised to the 2/8 power</u>
You subtract the % that the sale is and take it away from 100%. You get 75% then take the original price and divide it by .75

Let’s say y = 0
=> 4x – 8
=> 4x / 4 = 8 /4
=> x = 2
So the point is (2 , 0).
Now, we have 2 forms, the (2,0) and the (-4, 3)
=> (y2 – y1)(x2 – x1) = m
=> m = (0 - 3)(2-(-4))
=> m = (0 - 3)(2+4)
=> m = (-3)(6)
=> m = -1/2
Thus,
y = -1/2x + a
=> 0 = -1 + a so a = 1
y = -x/2 + 1</span>
