Answer:
f(5) = 21
Step-by-step explanation:
Step 1: Define
f(x) = 6 + 3x
f(5) is x = 5
Step 2: Substitute and Evaluate
f(5) = 6 + 3(5)
f(5) = 6 + 15
f(5) = 21
Answer:
b=-3
Step-by-step explanation:
4b+3=-9
-3 -3
subtract 3 from both sides like so. 3-3 cancels out. -9-3=-12.
4b=-12
youre left with 4b=12 so DIVIDE 4b by 4 and -12 by 4
4b/4=-12/4
4b divided by 4 is 1. -12 divided by 4 is -3
b=-3
plug -3 in for b to make sure its correct
4(-3)+3=-9
-12+3=-9
-9=-9
