Question

Evaluate the expression when a=-5 and y=7.

Answer 1

27

Explanation:

We are given that a = -5 and y = 7 and we are asked to evaluate the expression -4a + y.

To evaluate the expression, we would plug -5 for a and 7 for y into the expression.

-4a + y = -4(-5) + 7 = 20 + 7 = 27

So -4a + y = 27.
