Bis the midpoint of ac. ac =4x - 2 and ab =7. what is x, b. c. and ac?

sorry it was quite a bit but this is what I got

1) 2(7) = 4x - 2

2) 14 = 4x - 2

3) 16 = 4x

4) x = 4

5) AC = 4(4) - 2

6) don’t know

7)don’t know

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

570, the answer is 570, hope it
