Sarah deposits $1,400 into a savings account. The account earns a simple interest rate of 5% per year. After the first year what interest does the account earn?

$70

Step-by-step explanation:

1) lets use the interest formula:

I=PRT

Where I=interest

P=principal(starting amount of 1,400)

R=rate(0.05)

T=time(1)

Lets plug in our values into the formula:

I=1,400*0.05*1

I=70

The account earns an interest of $70

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.
