Answer:

B and C

Step-by-step explanation:

Minimum and Maximum points occur when the gradient of the function is equal to 0. Graphically this looks like a bend such that the function dips from decreasing to increasing (the gradient goes form being negative to positive) and vice versa.

A minimum point occurs where all the nearby values are higher than that of the point in question.

A maximum point occurs where all the nearby points are lower than the point in question.

By looking at the graph, there is a maximum point around (4.5, 1.5) which is consistent with B but not A (since A talks about a minimum point)

By looking at the graph, there is a minimum point around (0.5, 1.5) which is consistent with C.

I've highlighted areas of interest below so hopefully that's helpful :>

Tom made a vegetable pizza and a pepperoni pizza. he cut the vegetable pizza into 5 slices and the pepperoni pizza into 10 equal
Anon25 [30]
I may not be the best at this but I believe that Tom’s friends ate the same amount of pepperoni pizza to vegetable pizza because He cut the pizza into 5 slices as to the pepperoni into 10 slices is. The fraction of Vegetable to Pepperoni is 1/2 so 2 vegetable slices is the same amount as 4 slices because the pepperoni pizza is in smaller sizes compared to the Vegetable pizza.

The sum of all angles in an octagon is given by

180*(n-2) >>>>>>>>>with n = 8

180*(8-2) = 1080 degrees

A + B = 1080 .......where

A
  is the <span>angle of an octagon which is twice that of the other seven angles
</span><span>
B equals the sum of the other seven angles

If we assume each angle of B is equal to each other, then

B = x+x+x+x+x+x+x = 7x
</span>
And A = 2x

The equation that results is 

A + B = 2x +7x = 9x =1080

x = 120 degrees
2x = A = 240 degrees
