1 ≤ 3 - x
x + 1 ≤ 3 <em>added x to both sides</em>
x ≤ 2 <em>subtracted 1 from both sides</em>
Number line: ←----------------------·2 (fill in the dot at 2 since it is "equal to")

Answer:
D. 
and 
Step-by-step explanation:
The vertex of a function is controlled by the translations of the x and y value. Moving a vertex up and down is connected to the vertical position or the y-value. The y-value is the value that is added to the variable and is not squared.
Vertex form of a function is 
. In this case, k controls the vertical position of the vertex. If k is negative then the vertex will be moved down. So, if you want to move a vertex down by 5 units, then the k value must be -5.
Plug this into the formula to get the equation for k(x). This means that k(x) must equal 
.

In order to draw a perpendicular bisector you must have ruler , compass and a pencil.
Given nothing and we have to show the steps to draw a perpendicular bisector.
Perpendicular bisector is the line which divides the line into two equal parts and makes 90° angle on other line.
If we want to make a perpendicular bisector on a line then we have to follow the following steps:
1) First draw a line with the help of ruler on which we want to make perpendicular bisector.
2) Now take a compass and a pencil.
3) Put the pencil in the compass and strech the compass equal to half or little more of the length of the line.
4) Now put the compass on one end of the line and draw an arc on the line or may be just upward.
5) Now repeat the step 4 from other end.
6) Now draw a line from the point where two arcs intersects on the line.
7) It is the perpendicular bisector of the line.
Hence to draw a perpendicular bisector we require compass, ruler and a pencil.

No because you have to add all the results in each sample from 1-4+ together . meaning that in sample 1 , 38 people have 0 however 62 people have 1+
