Answer:
f(3) = -11, f(-7) = 19
Step-by-step explanation:
f(x) = -3x -2
1.
f(3) is the f(x) when x = 3 so where we see x in the equation we write 3 and calculate
f(3) = -3(3) -2 = -9 -2 = -11
2.
f(-7) = f( x= -7) = -3(-7) -2 = 21 -2 = 19
I say that the answer is E,F
2b/4=8 multiply both sides by 4
2b=32 divide both sides by 2
b=16
