Given: f(x) = x - 7 and h(x) = 2x + 3 write the rule for h(f( h(f(x)) = 2x - 11 h(f(x)) = 2x - 7 h(f(x)) = 2x - 4 h(f(x)) = 3x - 4

ANSWER

EXPLANATION

Given

and

We want to find

This means we substitute the function in to another function and evaluate.

This implies that;

We expand the parenthesis to obtain;

We simplify further to obtain;

Hence the correct answer is A

The correct answer option is h(f(x)) = 2x - 11

Step-by-step explanation:

We are given two functions:

 and  

and we supposed to find another function which is .

To find , we need to substitute the value of in the other function i.e. to get:

Therefore, the correct answer is h(f(x)) = 2x - 11.

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
