Answer:
a = 2.5, b = 1
Step-by-step explanation:
Given the 2 equations
4a = 5b + 5 → (1)
2a = 3b + 2 → (2)
Multiplying (2) by - 2 and adding the result to (1) will eliminate a
- 4a = - 6b - 4 → (3)
Add (1) and (3) term by term to eliminate a
0 = - b + 1 ( add b to both sides )
b = 1
Substitute b = 1 into either of the 2 equations and solve for a
Substituting into (2)
2a = 3(1) + 2 = 3 + 2 = 5 ( divide both sides by 2 )
a = 2.5
Answer:
A. (2,-6)
Step-by-step explanation:
(×-2)²+(y+6)²=10
Equating it with
(×-h)²+(y -k)²=10
h = 2 & k = - 6
(h, k) = (2, - 6)
Answer:
See attached graph.
Step-by-step explanation:
To graph the equation y=2, find 2 on the y-axis. Mark a point. Through this point, draw a horizontal line through 2 that is parallel to the x-axis. This is the line.
