Answer:
question 1: the lower left hand graph represents that equation.
question 2: a+b = 180°
question 3: a = b
question 4: a + b = 90°
question 5: a + b = 90°
-4x - 7 +10x = -7 + 6x
Combine like terms on left side.
6x - 7 = -7 + 6x
Add 7 to both sides.
6x = 6x
Subtract 6x from both sides.
0 = 0
This means there are infinitely many solutions.
0.3, 1/3, 2/5, 2/3
