Actually Welcome to the Concept of the Graphs and plots,

since the given equation is a parabolic equation graph, hence we substitute every value to get the value of variable y.

1.) if x = -5 ,then 25-30-7 => y = -12

2.) if x = -1 , then 1-6-7 => y = -12

3.) if x = -6 , then 36 -36 -7=> y = -7

4.) if x = 0 , then 0+0-7 => y = -7

hence all values are proved above

The decorating committee for a school
Schach [20]

Answer:

D. 160

Step-by-step explanation:

This question can be solved by proportions, using a rule of three.

In this question:

For each 3 white carnations, 5 yellows are needed, which leaves us with 8 total carnations. So for 60 white, the total is:

3 white - 8 total

60 white - x total

So

3x = 60*8

Dividing both sides by 3

x = 20*8 = 160

The correct answer is given by option D.
