9. Heather purchased a new $1,500 laptop by using a credit card with a 17% interest rate.
She will pay off the balance in 2 years by
paying monthly payments of $74.16. Calculate
Heather's total cost of repayment.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

3x + 4y -25 =0 represents the amount of change sianna should recieve

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
