Answer:
<em>Assuming person A and person B are part of the 7 people</em>, there are 10 ways the 7 people can line up if A needs to be first or last and B needs to be in the middle.
Step-by-step explanation:
There are 2 places for A (first, last) and 5 places for B (anywhere but first or last). 2 x 5 = 10.
X- 6/4=7
x-6=7×4
x-6=28
x=28-6
x=22
Answer:
y-6 = 2 (x-5)
Step-by-step explanation:
point slope form
y-y1 = m(x-x1)
y-6 = 2 (x-5)
Answer:
C.
Step-by-step explanation:
I can explain in comments if needed, but c is the correct answer :)
Answer:
