julia-pushkina [17]

Answer:

Red line

Step-by-step explanation:

2y+x=0

2y=-x

y=-x/2

Put the equation into y=mx+b so you would need to subtract the x to put it on the right side so then you’ll have 2y=-x+0 then divide by 2 to get the y by itself then you’ll have y=-2x+0 that means the line would be negative and the y-intercept is 0 and the only line that follows that is the red line.

A vet borrows $12,000 for 4 years. The total interest paid was $960. What was the interest rate on the loan?
Alchen [17]

Answer:

2% per year.

Step-by-step explanation:

Solving our equation

r = 960 / ( 12000 × 4 ) = 0.02

r = 0.02

converting r decimal to a percentage

R = 0.02 * 100 = 2%/year

The interest rate required to

accumulate simple interest of $ 960.00

from a principal of $ 12,000.00

over 4 years is 2% per year.
