12. A $20,000 investment earned a simple interest rate of 5.4%. How much interest was earned in one year?

18,920.00

Step-by-step explanation:

discount = x

original price = $20,000

discount% = 5.4%

x/20,000 = 5.4/100

x · 100 = 5.4 · 20,000

100x = 108,000

100x/100 = 108,000/100

x = $ 1,080.00

Sale price = original $ - discount $ = final answer

$20,000 - $1,080 = $18,920.00

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
