1. you purchase a car using a $20,000 loan with a 5% simple interest rate. (a) suppose you pay the loan off after 4 years. how much interest do you pay on your loan? show your work. (b) suppose you pay the loan off after 2 years. how much interest do you pay on your loan? show your work. (c) do you pay more interest if you pay the loan off after 4 years or after 2 years? any body go to k12

So basically all you do is this, on your assignment youll see words and stuff that are in colors. They also give you a formula for that. Its really easy.

So, you have 20000, 5%(0.5), 4 and 2. 20000 is blue, 5%(0.5) is orange, 4 and 2 are purple. So you do 20000 x 0.5 and you get 10000. So now you do 10000 x 4 x 2 and you get 80000xxx(or just 80000).

Or do 10000 x 4. Then after that take the result of 10000 x 4 and do x2. :)

I think I should the work enough, and good luck with the assignment.

i think the answer is seven, for if i'm being useless °ω°

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
