Answer: (4, -9)
<u>Step-by-step explanation:</u>
Use elimination method. Manipulate one (or both) equations to eliminate one of the variables and solve for the remaining variable. <em>I will be eliminating y</em>
6x + y = 15 → 2(6x + y = 15) → 12x + 2y = 30
-7x - 2y = -10 → 1(-7x + 2y = -10) → <u> -7x - 2y = -10</u>
5x = 20
x = 4
Next, replace "x" with "4" into either equation and solve for y.
6(4) + y = 15
24 + y = 15
y = -9
<u>Check:</u>
Plug in x = 4 and y = -9 into the other equation to verify it makes a true statement.
-7x - 2y = -10
-7(4) - 2(-9) = -10
-28 - -18 = -10
-28 + 18 = -10
-10 = -10 
Answer:7.776
Step-by-step explanation:
First, start off with the x-axis. -6.5, 1 becomes 6.5, 1. This is because point T is 6.5 to the left of the x-axis line, so our new point would be 6.5 to the right of the x-axis line. Same thing for the y-axis, (6.5, 1) would become (6.5, -1).
3. You purchase a car using a $20,000 loan with a 5% simple interest rate.
(a) How much interest do you pay on your loan if you pay off the loan in 4 years? Show your work.
(b) How much interest do you pay on your loan if you pay off the loan in 2 years? Show your work.
(c) How much interest do you save by paying the loan off in 2 years instead of 4? Show your work. Answer:
X * .65 = 143
Divide both sides by .65.
x = 220
143 is 65% of 220.
