2 answers:
Answer:
-48
Step-by-step explanation:
We are given the expression:
and asked to evaluated when x= -6 and y=9. Therefore, we must substitute -6 in for x and 9 in for y.
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Multiply -8 and 9 ⇔ -8*9= -72
Multiply -4 and -6 ⇔ -4*-6=24
Add 24 to -72.
The expression -8y-4x when evaluated at x=-6 and y=9 is equal to -48.
