Two siblings edwin and rhea are both going skiing but choose different payment plans. edwin's plan charges $45 for rentals and $5.25 per lift up the mountain. rhea's plan was a bundle where her entire day cost $108. set up an inequality that models the number of trips, n, up the mountain for which edwin will pay more than rhea. solve the inequality. also, what is the greatest amount of trips that edwin can take up the mountain and still pay less than rhea? explain how you arrived at your answer.

on friday there were 15 birds

-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
