Hello!

Recall that the equation of an exponential graph is:

We can see from the graph there is a y-intercept at y = 5. Plugging in 0 for x results in:

Solve for b by plugging in another point on the graph:

Write the final equation:

You can calculate the area of the whole pizza according to the formula: S=1/2*π*r². And the area of 8 piece is 1/8S while the area of 12 piece is 1/12S. The answer should be 1/8S-1/12S=4/3π.
Answer:
x = 5, 4 have a good night hope this is right if not im sorry
Step-by-step explanation:
your welcome
Your answer should be 264.
The answer is B) (-1,9).
I would suggest graphing this in order to find your solution however. Graph (-2,5) on a graph, then go up four units and over to the right one. Keep going until you find your point (-1,9).
