Answer:
y=5x-2
Step-by-step explanation:
divide to get y by itself
-5x+y=-2
move the x to the other side by adding it to both sides
y=5x-2
Depends how long each call is.
80 people divided by 4 phones is 20 rotataions on the phone.
If each call is 2 minutes that’s 20x2 = 40 minutes.

Step-by-step explanation:
Equation of a circle:
The equation of a circle with center
and radius r is given by:

Center: (−2, −5); radius= 1
This means that
. So



This is the equation of the circle.
Answer:
x ≥ 6; see below for a graph
Step-by-step explanation:
First inequality
7x -6 > 8
7x > 14 . . . . . . add 6
x > 2 . . . . . . . .divide by 7
Second inequality
3x+4 ≥ 22
3x ≥ 18 . . . . . . subtract 4
x ≥ 6 . . . . . . . . divide by 3
The values of x that will satisfy both inequalities are x ≥ 6. (All of those values are > 2.)
The solution to the inequalities is x ≥ 6.

Your graph will have a solid dot at x=6, indicating 6 is part of the solution set. It will be shaded to the right, with an arrow at the right end.
