A recipe calls for 5.4 cups of flour to make four regular batches of cookies. Shiloh needs to make multiple batches of cookies. A.) Represent this situation with an equation. B.) What is the constant of proportionality? How can you identify it in an equation? C,) How can you use an equation to determine if a relationship is proportional?

C =1.35f The constant of proportionality is the coefficient of the variable. Here it is 1.35.

If the equation can be used to calculate the change in the output and the output changes at a constant rate that matches the constant of proportionality,. It is proportional.

Step-by-step explanation: Given:

4C = 5.4f where C represents the batches of Cookies and f represents the cups of flour.

You need to find the amount of f per C.

So divide both sides by 4.

C= 5.4/4

C= 1.35f

This means that each batch of cookies requires 1.35 cups of flour.

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
