Answer:
Step-by-step explanation:
Solve each equation and compare the solutions
1.
- 2(a - 1.1) = 5.8
- a - 1.1 = 5.8/2
- a - 1.1 = 2.9
- a = 2.9 + 1.1
- a = 4
2.
- (5/2)b - 2 3/4 = 7 1/4
- 2.5b = 7 1/4 + 2 3/4
- 2.5b = 10
- b = 10/2.5
- b = 4
Both a and b have same value

Answer:
The answer is H.
Step-by-step explanation:
There is no "b" in this y = mx + b, so it has to go through zero, eliminating the bottom two. If we insert y = 2(1), the point should be at (1, 2), and if when looking at the possible answers, we can go with letter H.
