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
Answer:
Explanation:
5 1/6 pounds of graphs are bought for $7.75, meaning 1 pound costs
And we need to compute the division above.
The first step is to convert the mixed number 5 1/6 into an improper fraction.
Now, it is true that
multiplying 5 by 6/6 gives
