Hi there!

To solve this using substitution, we substitute the value of y in the equation.

5x + 8 = 8x + 9

Now, we simplify.

8 = 3x + 9
-1 = 3x

x = -1/3

We plug the value of x in,

y = 5 (-1/3) + 8
y = -1 2/3 + 8

y = 6 1/3

Hope this helps!

A certain college graduate borrows $8000 to buy a car. The lender charges interest at an annual rate of 10%. Assuming that inter

Answer:

The payment is $k=\$3216.92$ .

Interest paid during the 3-year period is $I_{T}=\$1651.76$

Step-by-step explanation:

The Payment amount

We are going to use the formula below with $VP=\$8000, i=10\%$ and $n=3$ .

$k=\frac{VP}{[\frac{1-(1+i)^{-n}}{i}] } =\frac{8000}{[\frac{1-(1+0.1)^{-3}}{0.1}] }=3216.92$

Interest paid during the 3 year

First period

$I_{1}=VP*i=8000*0.1=800$

$CS_{1}=k-I_{1}=3216.92-800=2416.92$

$Balance_{1}=VP-CS_{1}=8000-2416.92=5583.08$

Second period

$I_{2}=B_{1}*i=5583.08*0.1=558.31$

$CS_{2}=k-I_{2}=3216.92-558.31=2648.61$

$Balance_{2}=VP-CS_{2}=5583.08-2648.61=2924.47$

Third period

$I_{3}=B_{2}*i=2924.47*0.1=292.45$

Sum of Interest paid during the 3 years

$I_{t}=I_{1}+I_{2}+I_{3}=800+558.31+292.45=1651.76$

Two angles of a triangle measure 55° and 20°.

The answer is c because of the fact that if the 2 angles at 55 and 20 that means that you have to add them together and get to 180 for the triangle to be true
