Given: f(x) = x - 7 and h(x) = 2x + 3
Write the rule for f(h(x)).
Of(h(x)) = 2X-7
f(h(x)) = 2x - 4
f(h(x)) = 3x - 4
f(h(x)) = 3x - 7
DONE

f(h(x)) = 2x - 4

Step-by-step explanation:

Substitute x = h(x) into f(x), that is

f(h(x))

= f(2x + 3)

= 2x + 3 - 7

= 2x - 4

a. 3/4 ÷ 1/8 = 6

step-by-step explanation:

in the question, the number line represents 3/4 divided into 6 equal units. each arrow represents a unit and there are a total of six arrows.

the size of each unit is 1/8 as shown.

showing that 1/8 divides 3/4 into 6 divisions:

3/4 ÷ 1/8

= 3/4 x 8/1

= 3/1 x 8/4

= 3 x 2

= 6

hence, the number line represents six divisions given by 3/4 ÷ 1/8.
