Answer:

x=4

Step-by-step explanation:

it tel you that f(x) = 7 so replace "f(x)" for 7 in the equation. You then get 7 = 4x - 9 so now you solve for x. You have to isolate x so you add 9 to the other side since you do the opposite of -9. Once you add 9 and 7, then divide the answer by 4. You should get 4 = x.

Work:

f(x) = 4x - 9

7 = 4x - 9

7 + 9 = 4x

16 = 4x

16 ÷ 4 = x

4 = x

Patty made a banner that has an area of 112 square inches. The length and width of the banner are whole numbers. The length is 7

Answer:

The width of the banner is 4 inch and the length of the banner is 28 inch

Step-by-step explanation:

Given

Length is seven times its width

Let the width be "X", then length would be 7X

The banner is of rectangular shape.

Its area is 112 square inches

$X* 7X = 112\\7X^2 = 112\\X^2 = 16\\X = 4$

Hence, the width of the banner is 4 inch and the length of the banner is 4*7 i.2 28 inch
