Joe is taking part in a run for charity. He has earned $250 in pledges just for running and $40 in pledges for every mile he run
Harlamova29_29 [7]

im in middle school taking algebra 1 rn, but im pretty sure the equation is similar to 40x(40 pledges every mile) + 250(how much he already has from running) = y(the unknown variable).

so the equation would be 40x+250=y and you solve that to get the expression of how much he makes per mile

The system of equations 2y = 14 - 2x and y=-x+ 7 is
elena-s [515]

Answer:

  • Infinitely many solutions

Step-by-step explanation:

<u>Given system:</u>

  • 2y = 14 - 2x
  • y = -x + 7

<u>Divide the first equation by 2 and rearrange:</u>

  • 2y/2 = 14/2 - 2x/2
  • y = 7 - x
  • y = -x + 7

We got the same equation with the second one. It means we have two of the same lines overlapping.

This gives us infinitely many solutions.
