Answer:
(6 , -9) (7, -9)
Or
(6, 11) (7, 11)
Step-by-step explanation:
Given: Two of the vertices of a rectangle are (6,1) and (7,1)
Perimeter= 18 units
To get the value of "x"
The distance between Two point can be calculated as (6-7)=-1
Then x= -1
We can get the value of "y" by using expression for perimeter,
The perimeter P= 2x+2y=18
= 2(-1)+2y= 18
-2+2y=18
2y=18+2
2y= 20
y=10
The "y" coordinate can move up or can move down
y1=( 1-10)=-9
Or
y2=( 1+10)=11
Hence, the two other points are;
(6 , -9) (7, -9)
Or
(6, 11) (7, 11)
Answer:
28
Step-by-step explanation:
<em> -10 -10 -10 -10</em>
<em>68 </em>→ <em>58 </em>→ <em>48 </em>→ <em>38 </em>→ <em>28</em>

Answer: 24
Label the time slots as A,B,C,D
For time slot A, he has 4 candidates to pick from. Then for time slot B he has 3 choices left (he doesn't want to interview the same person again), and C has 2 choices, with D having just one choice. Effectively we start at 4 and count our way down to 1. We will multiply these values out.
Overall, Bob has 4*3*2*1 = 24 different ways to arrange the candidate interviews. This is known as a permutation because order matters.
Answer:
4 is not the constant. 2 is.
Step-by-step explanation:
In the following equation: y = 4x + 2
x and y are variables. x can be any given number, and y would be the resulting answer.
4 is not the constant, because the product it will produce varies on what x will be.
2 is a constant, because it will not change regardless what is put into x. It will continue to stay as 2.
