Answer:
10 three-point questions and 14 five-point questions.
Step-by-step explanation:
x+y = 24
3x+5y = 100
We can solve this system of equations using elimination. In order to do this, let's first multiply the first equation by 3...
3x+3y=72
3x+5y=100
Now, subtract the first equation from the second equation...
2y=28
Divide both sides by 2
y=14
Plug this back into any of the equations to solve for x...
x+14=24
x=10
There were 10 three-point questions and 14 five-point questions
Answer:
B
Step-by-step explanation:
Look at the X and Y coordinates carefully. X and Y coordinates are swapped and Y coordinate got negative sign.

Answer:
C
Step-by-step explanation:
From the table we see that

Thus, the inverse function has the rule

This gives us that ordered pairs

are on the graph of the inverse function
