Answer:
A graph titled Kristine's Savings has money earned on the x-axis and money saved on the y-axis. A line goes through points (20, 0) and (25, 5).
Step-by-step explanation:
If Kristine spends $20 and saves the rest when she gets paid, the amount she saves should always be 20 less than the amount she earned.
The points (20, 0) and (25, 5) accurately represent this, where x is how much she earns and y is how much she saves.
(20, 0) represents her earning $20 and saving $0, because she spends $20 every time she gets paid.
(25, 5) represents her earning $25 and saving $5, because she spent $20.
So, the correct graph is A graph titled Kristine's Savings has money earned on the x-axis and money saved on the y-axis. A line goes through points (20, 0) and (25, 5).

Answer:
48h
Step-by-step explanation:
Manny's amount of pictures will be represented by 36h, since he takes 36 every hour.
Colby's amount will be represented by 12h, since he takes 12 per hour.
Add these two together to get an expression:
36h + 12h
= 48h
So, 48h is the expression that can describe the combination of both of their pictures.
a. The lightbulb uses the energy of 960 W or 9.60 kW.
Step-by-step explanation:
Step 1:
To determine the energy used by the appliances we need to understand the equation
To determine the energy used, we multiply the power of the appliance with the amount of time it has been used for.
Step 2:
The lightbulb has a power of 60 W and is used for a period of 16 hours.
The energy used by the lightbulb 
W = 0.96 kW.
The toaster oven has a power of 1,500 W and is used for 0.75 hours.
The energy used by the toaster oven 
W = 1.125 kW.
