PLEASE HURRY Review the graph of . On a coordinate plane, a parabola opens to the right. It goes through (0, 8), has a vertex at (negative 3.5, 2), and goes through (0, negative 4). Everything to the left is shaded. Which justification can be used to demonstrate the graph is correct? Boundary values are included as part of the solution set. The positive coefficient StartFraction 1 Over 10 EndFraction indicates the parabola opens up. The coefficient of the y2 term is a fraction, so the parabola opens to the right. Shading is to the left because (0, 0) does not satisfy the inequality.

You would get a answer that is negative, and you would want to how to make the shaded value in there and it will help you, find the answer

Step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
