Please solve and show work pleasee

Step-by-step explanation:

y=-x+2 equation 1

y=3x-2 equation 2

sub equation 1 into 2

-x+2=3x-2

-x+2-3x+2 =0 (bring everything to one side and to equal 0)

-4x+4=0 (collect like terms and go with the sign given)

-4x=-4 (bring 4 over to the other side to isolate)

-4x/-4=-4/-4 (divide to isolate)

x=1

y=-3x+3 equation 1

2x+y=1 equation 2

y=-2x-1 Rearrage equation 2 (now equation 3)

sub equation 1 into 3

-3x+3=-2x-1

-3x+3+2x+1 =0 (bring everything to one side and to equal 0)

-x+4=0 (collect like terms and go with the sign given)

-x=-4 (bring 4 over to the other side to isolate)

1 is c

2 is a

3 is a

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
