So you just subsitute -3 for x
f(-3)=-(-3)+15
f(-3)=3+15
f(-3)=18
answer is C
18
Answer:
Well it would be 100 days
Step-by-step explanation:
Because they had pizza every ten days and if you add 5 days a week that's 50 days they sell pizza. If your talking corn they sell it every 4 days times 5 days a week that's 20 days of corn. Then you do 50 x 20 and then you get 100 days of pizza and corn, so it would be 100 days before they sell pizza and corn together again!
Answer:
s=-4
Step-by-step explanation:
- combine like terms on each side and get 3s-12=6s
- subtract 3s from both sides to get -12=3s
- divide both sides by three and get s=-4
Distribute the two: 2x + 6 = 18
Subtract the six: 2x = 12
Divide by two: x = 6
That's your answer!
