Rhianna is baking a cake and some cookies for a party. She used cups of flour for the cake. For each tray of cookies, she needs 2 2 cups of flour. She decides to use at least 15 cups of flour for the cake and the cookies.
Assuming she can make fractional trays of cookies, how many trays, x, can she make? Select the inequality that includes the
minimum number of trays of cookies Rhianna can make

answer: 5000

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
