Question

Evaluate the following expression when X=-4 and Y=4

Answer 1

Answer:

256.25

Step-by-step explanation:

$\dfrac{x^6 - x}{4y} =$

$= \dfrac{(4)^6 - (-4)}{4(4)}$

$= \dfrac{4096 + 4}{16}$

$= \dfrac{4100}{16}$

$= 256.25$

Answer 2

Answer: y = x^{2} - 16

Step-by-step explanation: Work backwards to find the factors from the root, then multiply the factors together.
