Jade borrowed $5,000 from a bank to buy a car. She will pay back the loan in 3 years with simple interest, at an interest rate of 18% per year. What is the total amount that she will pay after 3 years? pls i will give

Step-by-step explanation:

borrowed amount -$5000

interest rates -18% per year(3 years interval)

18/100 × 5000/1 =

90000/100=900

900×3=

2700

I.e in 3yrs she will pay

5000+2700=$7700

a = -2

Step-by-step explanation:

f(x)=ax+b

f(2)=1  

f(-3)=11

f(2) = 1   means   2a+b =1

f(-3)=11   means   -3a + b = 11

Subtracting the two equations

-(-3a +b =11) becomes 3a -b = -11   so we can add

2a+b =1

3a - b = -11

5a = -10

Divide by 5

5a/5 = -10/5

a=-2
