Question

If x = −3 and y = −6, what is the value of 3x + 4y + 15?

A 48
B 35
C -18
D -48

Answer 1

Explanation:

x=-3 and y=-6 ⇒

1. 3*x=3*(-3)=-9
2. 4*y=4*(-6)=-24
3. 15

so if we add these numbers together, we will have :

-9 + (-24) + 15 = -18

and it is C .

Answer 2

C. -18

Explanation:

3(-3)+4(-6)+15=

-9+-24+15

-33+15=-18
