Find the solution to the system of equations.

x=1, y=-4

Step-by-step explanation:

There are different ways to solve system of equation

In your case, since they are all put y on one side, then we should use substitution.

we should substitute y

-7x+3=-x-3

-7x+x=-3-3

  -6x=-6

      x=1

substitute x into any one of the equation to find y

y=-7x+3

y=-7×1+3

y=-7+3

y=-4

y=-x-3

y=-1-3

y=-4

the distance between point a and point b is 6 units

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
