Answer:
see explanation
Step-by-step explanation:
The solutions to the systems of equations are at the points of intersection of the 2 graphed functions.
1
There are 2 points of intersection , so 2 solutions at
(0, - 3 ) and (4, 5 )
2
There is 1 point of intersection, so 1 solution at
(- 2, 5 )
3
There are no points of intersection , so no solution
Measure of x: 10x+50=180
10x=130
x=13
