Answer:

not proportional

Step-by-step explanation:

We can use cross products to determine if the ratios are proportional

50         10

------ = -----------

32           8

50*8 = 10 *32

400 = 320

This is not true so they are not proportional

Which are steps that could be used to solve 0 = 9(x2 + 6x) – 18 by completing the square? Check all that apply.
Fiesta28 [93]

Answer:

18+81=9(x^{2}+6x+9)

11=(x+3)^{2}

Step-by-step explanation:

we have

0=9(x^{2} +6x)-18

Adds 18 both sides

18=9(x^{2} +6x)

Complete the square

18+81=9(x^{2}+6x+9)

99=9(x^{2}+6x+9)

Divide by 9 both sides

11=(x^{2}+6x+9)

Rewrite as perfect squares

11=(x+3)^{2}

First you multiply 44.94 and .07 (the decimal equivalent of 7%) which gives you 3.1458. You take 3.1458 and add it to 44.94 (since it's an additional fee) and that gives you 48.0858
