Answer:
a.) DomainL: -2 ≥ x < 1 Range: 1 ≥ y < 2
b.) DomainL: -2 > x < 2 Range: -2 > y < 2
Step-by-step explanation:
look up what the open and closed dots mean
understand how to determine values on the y or x axis
I think you're missing a bit of the question. If her savings can be modeled by x...?
Answer:
(6,2)
Step by Step explanation:

4- solve the equation to find X
5 - put answer in correct format (x,y)
Answer:
Step-by-step explanation:
Five equivalent ratios:
