You add -3x to both sides of the equation:
-3x+3x-y=8-3x you get -y = 8-3x
and then you multiply both sides by -1 and you get y = 3x-8

Answer:

First one: C. Second One:C.

Step-by-step explanation:

Kate purchased a car for $23,000. It will depreciate by a rate of 12% a year. What is the value of the car in 4 years?

a) $13,935.76

b) $12,874.57

c) $13,792.99

To solve this this is an exponential function. The price started at $23,000 and depreciates at 12% so the equation is f(x) = (23,0000)(1-0.12)^4. When calculated results with 13792.99328 which is C.

A rare coin is currently worth $450. The value of the coin increases 4% each year. Determine the value of the coin after 7 years.

a) $613.98

b) $546.78

c) $592.17

To solve this this is also an exponential function. The price started at $450 and  the coin increases 4% each year so the equation is f(x) = (450)(1+0.04)^7. When calculated results with 592.169300656 which is c.

Clarke borrows $16,000 to buy a car. He pays simple interest at an annual rate of 6% over a period of 3.5 years. How much does h
mr Goodwill [35]

Answer:

The total amount he will altogether be: $19360

Step-by-step explanation:

Given

  • Amount Borrowed = P = $16,000
  • Interest rate = r =  6% = 6/100 = 0.06
  • Time period = t = 3.5 years

To determine

  • Amount of interest = I
  • Total Amount altogether = A

Using the formula

I = Prt

substituting the values P = 16,000, r = 0.06, t = 3.5 years

I = 16,000 × 0.06 × 3.5

I = $3360

Thus, the interest amount = $3360

Therefore, the total amount he will altogether:

A = P + I

A = 16,000 + 3360

A = $19360

Therefore, the total amount he will altogether be: $19360
