Answer: A
(He has the side lengths in the wrong place in the cosine ratio)
If a solution(s) exists y=y so we can say:
x^2-3x=-2x+2 add 2x to both sides
x^2-x=2 subtract 2 from both sides
x^2-x-2=0 factor
(x-2)(x+1)=0
So x=-1 and 2, using y=-2x+2 we find:
y(-1)=4 and y(2)=-2
So the two solutions occur at the points:
(-1,4) and (2,-2)
Simplify:
7x+3=7x-3
Now 7x goes away and you get 3=-3, which cannot be true, so there is no solution
Your income is the money you receive or acquire it's the inflow and your total expenses are the money you spent it's the outflow
The answer would be 5,875.00
