Hello!


This question is an example of function composition.


Given, f(x) = 3x - 5, find f(x - 1). For this problem, we substitute x for (x - 1).


f(x - 1) = 3(x - 1) - 5

f(x - 1) = 3x - 3 - 5

f(x - 1) = 3x - 8


Therefore, the answer is choice D, f(x - 1) = 3x - 8.

Forty five percent of middle schools have a horse as a mascot. If there are 420 middle schools how many have a horse as a mascot
allochka39001 [22]
189
Because you have to turn it into a percentage in order to know how many per 1 percent. So multiply 420 by 100 and get 4.2 then you multiply it by 45 and you get 189 so 179 schools have a horse mascot

Answer:

X=1

Step-by-step explanation:

Look at that website. The part says that (ab*ad)=(ac*ae)

Doing that, we get

9*(9+11x)=10(10+8x)

81+99x=100+80x

19x=19

X=1
