Answer:
10
Step-by-step explanation:
Divide by 2.5: 2.5(12.75x+24.50)/2.5 = 188.75/2.5 .
simplify: 12.75x + 24.50=75.5 .
subtract 24.50 from both sides
simplify: 12.75x = 51 .
x= 4.
The second one because domain refers to x, and since at (-3,-4) the point is hollow, the sign should be < without the line under it
