In order for a function...to be called a function , is that for every x, there must always only be one y. Two x's can have the same y, but the same x can't have two separate y's. One way to test this is the vertical line test. You basically put up a vertical line on the graph. The artificial line (you can do it with your finger, pencil, etc.) should only intersect once on the graph. So, take your pencil, and hold it up to down (like this | ) on your monitor. You see that when you do that, it intersects with the graph twice. That means it DOESN'T pass the vertical line test, which means it is not a function (Function are not always straight lines, which is why the first two are wrong). So, the answer is
D)
Start at 0 and go back 7 yards for their loss. You are not at -7 on the number line.
Move 12 to the right because of the gain. It takes 7 or those 12 just to get back to zero and you can still move 5 more to the right. You will wind up with a gain of 5 yards. (+5)
Question:
Which of the following represents two lines that are coplanar and do not intersect?
A. Perpendicular
B. Skew
C. Parallel
D. Intersecting
Answer:
Two lines that are co -planar and do not intersect is Parallel.
Step-by-step explanation:
Two lines are said to be parallel if they lie in the same plane, and are the same distance apart over their entire length.Each line has many parallels. Any line that has the same slope as the original will never intersect with it. Hence Parallel Lines would never cross, even if extended forever. Technically parallel lines are two coplanar which means they share the same plane or they're in the same plane that never intersect
Answer:
9:1or 1:9
Step-by-step explanation:
The original ratio is 36:4 but we have to simplify
36÷4=9
4÷4=1
so in the end of it you receive a ratio of 9:1 or 1:9
