Answer:
slope= -¾

Step-by-step explanation:
3x +4y= 9
Let's rewrite the equation into the form of y= mx +b (known as slope-intercept form), where m is the slope and b is the y-intercept.
Keep the y term on the left-hand side of the equation and move all the other terms to the right-hand side.
4y= -3x +9
For the coefficient of y to be 1, divide both sides of the equation by 4.

Step-by-step explanation:
The area of the top surface of this wedge is 14.14 inches².
<h3>What is the area of a sector?</h3>
The shape of the top surface of the wedge assumes the shape of a sector. So, to determine the area of the top surface of this wedge, we need to find the area of the sector.
Area of a sector = 
where;
- Central angle θ = π/2
- radius = 3 inches
Area of a sector = 
Area of a sector = 
Area of a sector = 14.14 inches²

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.
