(35 points) A movie theater has special pricing for large group events. for the first 7 people, the tickets cost $10 per person. for every person after that, up to a group of 20 people, the tickets cost $5 per person. the function c gives the total cost, in dollars for a youth group to take a special trip to the movie theater.

A. Is Function C a piecewise function? Please explain your reasoning.
B. Draw a graph to represent C.
C. Describe as completely as possible, the domain of C.
D. Describe as completely as possible the range of C.
Thank you :)

c. 16 units

step-by-step explanation:

mark brainliest and have a great day!

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

answer: finding the extract measurements and knowing the points

step-by-step explanation:

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
