Answer: -18 ==> C
Step-by-step explanation:
x = −3 and y = −6
3x + 4y + 15=
3(-3) + 4(-6) + 15=
-9 + (-24) + 15 =
-9-24+15=
-(9+24)+15=
-33+15=
-(33-15)=-18 ==> C
Answer:
c) -18
Step-by-step explanation:
Given that,
→ x = -3
→ y = -6
Let's solve the problem,
→ 3x + 4y + 15
→ (3 × -3) + (4 × -6) + 15
→ -9 - 24 + 15 = -18
Thus, the solution is -18.
