Answer:
if f(x)= -4x+3
f(-5)= 23
Step-by-step explanation:
first you substitute x for -5
f(-5)= -4(-5)+3
then you multiply
-4(-5)
f(-5)=20+3
you get the positive 20 because negative times negative equals positive
then you just add the rest (20+3) which will give you your answer
f(-5)= 23
Answer:
30=15

I’m pretty sure it would be a and b
8 is 6.2
9 is 7
The pattern here is +0.8.
4.6 - 3.8=0.8
5.4-4.6=0.8, and so on
