Answer:
The answer is C.
Step-by-step explanation:
Given the line segment ST. we have to give the instruction to construct the perpendicular bisector of line ST.
So to construct the perpendicular bisector of line our first step is to place the compass at one end of line and then adjust the compass more than half of line segment and draw the arc on each side of segment.
After that Keeping the same compass width, draw arcs from other end of line. Place scale where the arcs intersect, and draw the line segment.
So, the correct match is option C ) Place the compass point on point S and open the compass so that the pencil point is on the segment, but closer to point T than to point S. Draw an arc on each side of segment.
Y = -2x + 6
I think this is it
Answer:
x = 3
Step-by-step explanation:
First, distribute 3 into the parenthesis:
3(4 - 2x) = -2x
12 - 6x = -2x
Next, combine your x variables by adding +6x to both side:
12 - 6x = -2x (-6x and +6x cancel out)
+6x +6x
12 = 4x (divide 12 by 4 to get x by itself)
/4 /4
x = 3

Given
![DJs = 7](https://tex.z-dn.net/?f=DJs%20%3D%207)
![To\ pick = 4](https://tex.z-dn.net/?f=To%5C%20pick%20%3D%204)
Required
Determine the number of rankings
The term "ranking" as used in this question implies permutation and the required is calculated using:
![^nP_r = \frac{n!}{(n-r)!}](https://tex.z-dn.net/?f=%5EnP_r%20%3D%20%5Cfrac%7Bn%21%7D%7B%28n-r%29%21%7D)
Where
![n = 7](https://tex.z-dn.net/?f=n%20%3D%207)
![r = 4](https://tex.z-dn.net/?f=r%20%3D%204)
So:
![^nP_r = \frac{n!}{(n-r)!}](https://tex.z-dn.net/?f=%5EnP_r%20%3D%20%5Cfrac%7Bn%21%7D%7B%28n-r%29%21%7D)
![^7P_4 = \frac{7!}{(7-4)!}](https://tex.z-dn.net/?f=%5E7P_4%20%3D%20%5Cfrac%7B7%21%7D%7B%287-4%29%21%7D)
![^7P_4 = \frac{7!}{3!}](https://tex.z-dn.net/?f=%5E7P_4%20%3D%20%5Cfrac%7B7%21%7D%7B3%21%7D)
![^7P_4 = \frac{7 * 6 * 5 * 4 * 3!}{3!}](https://tex.z-dn.net/?f=%5E7P_4%20%3D%20%5Cfrac%7B7%20%2A%206%20%2A%205%20%2A%204%20%2A%203%21%7D%7B3%21%7D)
![^7P_4 = 7 * 6 * 5 * 4](https://tex.z-dn.net/?f=%5E7P_4%20%3D%207%20%2A%206%20%2A%205%20%2A%204)
![^7P_4 = 840](https://tex.z-dn.net/?f=%5E7P_4%20%3D%20840)
<em>Hence, number of ranking is 840</em>
