Find the perimeter of abc wirh vertices a(0,2) b(0,5) c( -6,2)

What is the ordered pair of m’ after point m (5, 6) is rotated 90° counterclockwise?

50 will mark show all use the linear combination method to solve the system of equations. explain each step of your solution. if steps are not explained, you will not receive credit for that step. 2x+9y= -26 -3x-7y=13

Solve the system of equations. 2x-2y=-4 and x+y=8. show work
