Answer:
B
Step-by-step explanation:
For y to be a function of x, x must only have one value for each y value.
In B, the number 10 comes up twice in the x row. Therefore, y is not a function of x.
Mr. duc asked to set up 450 chairs in a large hall. Perry puts 20 chairs in each row. He has already set up 15 rows of chairs
Each row consists of 20 chairs
He already set up 15 rows
So number of chairs he already set up = chairs in each row * number of rows
20 * 15 = 300
So , he already set up 300 chairs
Total chairs to set up is 450
Remaining chairs to set up = 450 - 300 = 150
So, 150 more chairs to set up

Answer:
D. Graph A
Step-by-step explanation:
First, notice the function can be factored easily:
So we can see that the function hits the y-axis at 2 points:
(-8,0) and (-2,0).
Which of the graphs in the picture show a parabola that hits the y-axis at those points? Graph A is the only option.
So the answer is D. Graph A
