Answer:
The graph is not a function of x because the line x = 0 intersects the graph at two points.
Step-by-step explanation:
This graph is not a function because it fails the vertical line test, since several vertical lines would intersect the graph at 2 points.
This answer choice is correct, as the line x = 0 intersects the graph at 2 points, (0, 2) and (0, -2).
Answer:
A
Step-by-step explanation:
Answer: a. point
Step-by-step explanation:
The answer above makes the statement true because a point on a graph is consists of values of x and y (x;y).
For every x you punch into the system, you get a value of y, and this can go on for all values that apply to the graph. This makes up a set of ordered pairs.

Answer:
SR =3
Step-by-step explanation:
SR + RQ = SQ
2x+23 + x+21 = 14
Combine like terms
3x+44 = 14
Subtract 44 from each side
3x+44-44= 14-44
3x = -30
Divide each side by 3
3x/3 = -30/3
x = -10
SR = 2x+23 = 2(-10)+23 = -20+3 =3
Answer: 3
Step-by-step explanation:
We can start by making an equation.
Since we know the total length of SQ we can add SR + RQ to equal SQ.
The parenthesizes are not necessary but they help for understanding the parts of the equation.
We will remove the parenthesizes and combine like terms.
Now subtract 44 from both sides to cancel it out from the side with x.
Now divide by 3 to isolate x.
So x = -10.
Now we can plug in the value of x into SR.
Solve
So SR = 3
