At the baseball field a bag of candy
is 2.50 and a bag of popcorn is 4.25. roman is planning to purchase 3 boxes of candy and x bags of popcorn. write an equation to find y ,the total price roman must pay.

y=4.25x+7.50

Step-by-step explanation:

3 times 2.50 = 7.50

cost of all the candy Roman is buying ^

you don't know how many bags of popcorn he's buying

y=4.25x+7.50

4.25 is the cost of each popcorn bag, x is how many boxes he will buy

y is the total price he pays

7.50 is the cost of the candy

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
