The function f is defined by f(x)=7x−5. use this formula to find the following values of f. f(3)

f(3) = 16

Step-by-step explanation:

f(x)= 7x-5

We want to find the value when x=3

f(3) = 7*3 -5

f(3) = 21-5

f(3) = 16

f(3) = 16

Step-by-step explanation:

Put 3 where x is and do the arithmetic.

... f(3) = 7·3 -5 = 21 -5 = 16

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.
