Answer:
The line passes through (4, -7) and (5, -10).
Step-by-step explanation:
When x = 4, y = 5 - 3(4), or 5 - 12, or -7. Thus the point (4, -7) lies on the graph. Similarly y = 5 - 3(5) = -10 when x = 5. Thus, the line also goes through (5, -10). Plot these two points and draw a line through them. Doing this will result in the desired graph.
10,10 and 20 cannot as 10+10=20 so there would be a triangle with no area.
The others can all be the sides of a triangle as 7+7>8, 7+6>11 and 2+8>9.
Answer:
2x-30
Step-by-step explanation:
5(x-3) = 5x-15
-3(x+5) -3x-15
(5x-15) + (-3x-15) = 2x-30
