Answer:

Yes!

Step-by-step explanation:

When we have problems like this we just plug them in. We take the -2 and we multiply it by the -5 to get a positive 10. We then add that to the +13 and it equals 23, so it works!
Yes!
You plug in the -2 into x and the 23 into f(x).

f(23)= 13-5(-2)
f(23)= 13+10
f(23)= 23
