At the start of the year, the balance in a married couple’s account is $1,750. They decide to each deposit $35 into the account each month. Which function represents the amount in the account n months after the beginning of the year? f(n) = 1,750 + 35n f, (, n, ) = 1,750 + 35, n f(n) = 1,750 + 70n f, (, n, ) = 1,750 + 70, n f(n) = 1,750n + 35 f, (, n, ) = 1,750, n, + 35 f(n) = 1,750n + 70

the answer is 31.27mph

answer: 88

step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
