Answer:
1. C, 2.C
Step-by-step explanation:
Here's why for the first one it's easy because we just solve y=2, x=3, so we select C, the next one however we have to know eliminate a variable, which in this case we can eliminate the y variable quite easily. So once we did that we got x=2, now we plug that in to the first equation and we get -y=1, which is equal to -1.

Answer:
$9816.37
Step-by-step explanation:
A=p(1+r/n)^nr
a= 4000(1+0.06/12)^(12*15)= 9816.374.
Steps to solve:
9|9 - 8x| = 2x + 3
~Divide 9 to both sides
|9 - 8x| = 2/9x + 1/3
~Solve absolute value (part one)
|9 - 8x| = 2/9x + 1/3
-74/9x + 9 = 1/3 (Subtracted 2/9x to both sides)
-74/9x = -26/3 (Subtracted 9 to both sides)
x = 39/37 (Multiplied 37/39 to both sides)
~Solve absolute value (part two)
|9 - 8x| = -(2/9x + 1/3)
|9 - 8x| = -2/9x - 1/3 (Distributed negative sign to left side)
-70/9x + 9 = 11/3 (Added 2/9x to both sides)
-70/9x = -28/3 (Subtracted 9 to both sides)
x = 6/5 (Multiplied 9/-70 to both sides)
Therefore, the solutions are x = 39/37 and x = 6/5

Answer:
Point B is the result of a 90° counterclockwise rotation.
Step-by-step explanation:
To get your answer we'll plug 0 in for x into the equation.
So, multiply 4*0 which equals 0.

Then we'll add 0 and 7 which leaves us with
The y-intercept of this equation is: 
To find the x-intercept of this equation we'll rewrite it as

Then we'll subtract 7 from both sides,

Now we'll divide each side by 4. Then simplify which brings us to our answer,
The x-intercept of this equation is:
