divide 15 hours by 75%
15 / 0.75 = 20
he was scheduled for 20 hours
Answer:
20
Step-by-step explanation:
60+x+100=180 is the equation we are asked to solve.
Using commutative property of addition you can rewrite as:
x+60+100=180
Using associative property of addition you can rewrite as:
x+(60+100)=180
Combine like terms/simplify:
x+(160)=180
x+160=180
Use subtraction property of equality to rewrite as:
x+160-160=180-160
Simplify both sides:
x+0=20
Apply the additive identity property:
x=20
So x=20.
Check.
60+x+100=180 with x=20:
60+20+100=180
80+100=180
180=180
The last line I have here is true so x=20 has been verified as the solution.
116 if you add 72 plus 43
Domain = Set of all real numbers, which is choice B
Range = Choice C)

The domain is the set of allowed x value inputs of a function. In this case, we can plug in any x value we want. The graph stretches forever in both directions along the x axis. This is shown by the arrows.So that's why the domain is the set of all real numbers.
The range is the set of outputs of a function. It is the set of possible y values. As you can see on the graph, the highest point is at (-1,3) which is the vertex.
The largest y value possible is y = 3. Any other y value smaller than this is possible. So the range is therefore

where y is a real number
