Answer:
x=10
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
7x-3 + 12x-7 = 180
Combine like terms
19x-10 = 180
Add 10 to each side
19x-10+10 = 180+10
19x = 190
Divide by 19
19x/19 = 190/19
x= 10

y = -4
The ordered pair is (9, -4).
First one is three i think
1) Discrete graph
2) Continuous graph
I hope this helps! I would check with someone else first though.
