Evaluate (x3 - 15) - (y + 6) for x = 4 and y = 1.

The answer to the function is - 10

42

Step-by-step explanation:

Open the bracket first

(X3-15) - (y+6)

X3-15-y-6

Collect like terms

X3-y-15-6

X3-y-21

And x is said to be 4, y to be 1

So let's substitute

(4) ^3 - (1) - 21

64-1-21

64-22

42

Therefore the final answer is 42
