I NEED SOMEONE WHO IS SUPER SMART! I NEED HELP! PLEASE. I WILL GIVE BRAINIEST Which of the following can be modeled with a linear function? Select all that apply.

a. The cost per visit to a community pool. The neighborhood charges a yearly fee to use the pool.

b. The cost to attend a show at the local theatre. Tickets are $12 each.

c. An endangered species population is decreasing by 15% each year.

d. The distance a bicyclist travels when cycling at a constant speed of 30 mph.

e. The population of a town growing at a constant rate each year.

PLEASE HELP!

I'm pretty sure it's C or E, as they are the only ones who go at a constant rate up or down.

Step-by-step explanation:

1e+27

step-by-step explanation:

-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
