Question

What is the value of 4x2−5y/2x
if x=−3
and y=6

Answer 1

After substituting x = -3 and y = 6 into the expression 4x^2 - 5y / 2x, we simplify it step by step to find that the value of the expression is -1.

Step-by-step explanation:

To find the value of the expression 4x^2 - 5y / 2x when x = -3 and y = 6, we substitute these values into the expression:

4(-3)^2 - 5(6) / 2(-3)

Simplifying,

4(9) - 30 / -6

36 - 30 / -6

6 / -6

Simplifying further,

-1
