Multiply each hourly rate by x ( time to complete the work) add it to the service call for each and then set the equations equal:

50 + 40x = 30 +45x

Subtract 30 from both sides:

20 + 40x = 45x

Subtract 40x from both sides:

20 = 5x

Divide both sides by 5

x = 4

What are the zeros of f(x) = x2 + 3x – 10?

Nady [450]

Step One
Factor f(x)
f(x) = (x + 5)(x - 2)

Step Two
The zeros occur when either (x + 5) = 0 or (x - 2) = 0

x + 5 = 0
x = -5

x - 2 =0
x = 2

Step 3
Record the zeros

2. So if you look there are three meat options meaning there is a one in three chance logical chance someone picks turkey (note when I say logical I mean that doesn't mean that this will be true in real life) and there is a one in two logical chance someone picks Swiss cheese.

3. So with a one in three chance logical meat option and a one two chance cheese option and.

4. Now knowing this it is simple math at this point as simple as $\frac{1}{3}$ x $\frac{1}{2}$
