Aschool spent $150 on advertising for a breakfast fundraiser. each plate of food was sold for $8.00 but cost the school $2.00 to prepare. after all expenses were paid, the school raised $2,400 at the fundraiser. which equation can be used to find x, the number of plates that were sold?

6x – 150 = 2,400

6x + 150 = 2,400

10x – 150 = 2,400

10x + 150 = 2,400

A. 6x-150=2400

X=425

Step-by-step explanation:

Solve.

6x-150=2400

First, you add 150 from both sides of equation.

6x-150+150=2400+150

Then, simplify.

2400+150=2550

6x=2550

Divide by 6 from both sides of equation.

6x/6=2550/6x

Simplify to find the answer.

2550/6=425

X=425 is the correct answer.

A. 6x-150=2400 is the correct answer.

6x – 150 = 2400

Step-by-step explanation:

Each plate of food was sold for $8, but cost the school $2 to prepare:

-2x + 8x = 6x

A school spent $150 on advertising for a breakfast fundraiser:

-150

After all expenses were paid, the school raised $2400 at the fundraiser:

6x – 150 = 2400

In case you want to solve it:

6x – 150 = 2400

+ 150 + 150

6x = 2550

___

66

x = 425

So, four hundred twenty-five plates were sold.

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

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
