Answer:

It has one solution (1,0)

Step-by-step explanation:

y = -2x + 2

y = 4x -4

Substitute the y's

4x - 4 = -2x + 2

Let's move the variables to one side

4x - 4 = -2x + 2

+2x       +2x

6x - 4 = 2

Lets move the constant to the other side

6x - 4 = 2

     +4   +4

6x = 6

Divide both sides by 6

6x/6 = 6/6

x = 1

Let go back to y = -2x + 2

Substitute the x with 1

y = -2(1) + 2

y = -2 + 2

y = 0

12. Make equation and plug in

13. Proportion

14. Finding a constant rate, and then manipulate




12. Where x is miles driven, and y is answer, and z is days
      19.95z+0.15x=y
      Plug in two values
      19.95 x 2 + 0.15 x 250 = y
      39.93+37.5 = y
      y=77.43

13. 5:2 as 175:x 
      5/2 = 175/x
      x = 70
      70+175=245

14. 260:5 = x:1
      260/5=x/1
      x = 52
      
      52:1 = y:9
      52/1 = y/9
      y = 468

I hope you understand the process.
