-3(x-5)=45
distribute
-3x+15 = 45
subtract 15 from each side
-3x = 30
divide by -3
x = -10
Answer:
B.
Step-by-step explanation:
If you rearrange the equation in b, you get
y=5(x-3)+15
This means that your f(1) is equal to f(3), or 15, and for each additional month, it increases by 5, which is what the table shows.
So therefore the answer is –42
Step-by-step explanation:
5*–7–7= –42
So what you will need to do is subtract 2x - 3x = -x, then subtract three from both sides 8 - 3 and the answer will be -x + 5
