Answer:

Yes

Step-by-step explanation:

In the first equation, sub in (-3x/2) for y:

3x+4y=12

3x+4(-3x/2)=12

3x-(12x/2)=12

3x-6x=12

-3x=12

x=-4

y=-3x/2

y=-3(-4)/2

y=12/2

y=6

Since x=-4 and y=6, (-4,6) is a solution.

Consumer Math TestYou borrow $13,000 to buy a car. You borrow the money for 4 years and the interest rate is 2.5%. How much inte

enot [183]

Answer:

You will pay $1,300 in interest.

The final price of the car is of $14,300

Step-by-step explanation:

Simple interest formula:

$I=P\ast r\ast t$

In which:

I is the interest

P is the principal(initial value of the investment, amount borrowed,...)

r is the interest rate, as a decimal

t is the time, in years.

In this question:

Borrow $13,000, so P = 13000

4 years, so t = 4

Interest rate of 2.5%, so r = 0.025

$I=13000\ast0.025\ast4=1300$

You will pay $1,300 in interest.

Final price of the car:

Principal plus interest.

$T=P+I=13000+1300=14300$

The final price of the car is of $14,300
