Thang decided to borrow ​$9000 from his local bank to help pay for a car. His loan was for 3 years at a simple interest rate of 9​%. How much interest will Thang​ pay?

2,430

Step-by-step explanation:

Use the formula:

I=PRT

to find interest

Where P stands for money borrowed

R= Interest Rate

T= Time

First convert 9% to decimal by moving decimal point 2 spaces back:

9% > 0.09

Then input it to the equation

I= 9000•0.09•3

Multiply to find

2,430

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
