Answer
x = 2 and y = 3
Use substitution
3x = 15 - 3 (13 - 5x)
x = 2
Plug in x
3 (2) = 15 - 3y
y = 3
Set p(x) = 0 and solve for x.
x^3 - 4x^2 + 3x - 12 = 0
x^3 - 4x^2 ... + 3x - 12 = 0, cut in half and factor
x^2 (x-4) ... +3 (x-4) = 0, regroup
(x^2 + 3) (x-4) = 0, set each part equal to zero and solve
x^2 + 3 = 0, subtract 3 from both sides
x^2 = -3, take square root of both sides
x = sqrt (-3) which is imaginary.
x-4 = 0, add 4 to both sides
x = 4
Since we do not want complex/imaginary numbers involved, our answer is 4. They will break even in 4 years.

Answer:
(-10,-6)
Step-by-step explanation:
When this point is reflected in the x-axis, the y-coordinates change from either positive to negative or negative to positive. The x-coordinates will not change.
Since the y-coordinates is originally positive, it will change to negative. Giving us our answer of:
(-10,-6)
You are solving for x here. To solve for x you need to isolate it onto one side of the equation. First multiply -4 into (-6x - 3) to get 24x + 12. Now that you have a simplified equation on both sides, subtract 12 from both sides to get 24x = 0. Because anything multiplied by 0 equals 0, x = 0.
