I'm giving away 16 points Elena and Jada each make money by helping out their neighbors.

Elena babysits. Her earnings are given by the equation y=8.40x, where x represents how many hours she works and y represents how much money she earns.

Jada earns $7 per hour mowing her neighbors’ lawns.

A. Who makes more money after working 12 hours? How much more do they make? Explain how you know.

B. What is the rate of change for each situation and what does it mean?

C. How long would it take each person to earn $150? Explain or show your reasoning.

i dony know

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
