I would assume that you would subtract 40 from 60 and get 20. (60-40=20) So I'd say 20 hours.
Step-by-step explanation:
Given
f(x) = 1/3x + 13
f^-1(x) = ?
Now
Let y = f(x)
or y = 1/3x + 13
Interchanging the role of x and y
x = 1/3y + 13
x - 13 = 1/3y
y = <u>x </u><u>-</u><u> </u><u>1</u><u>3</u>
3
Therefore f^-1(x) = <u>x </u><u>-</u><u> </u><u>1</u><u>3</u><u> </u>

Hope it will help you.
Answer:
Angle M = 63
Angle N = 96
Step-by-step explanation:
By exterior angle of triangle:
Angle M + Angle N = 159
(4y+3)+(6y+6)=159
y = 15
Angle M = 4y + 3 = 4(15) + 3 = 63
Angle N = 6y + 6 = 6(15) + 6 = 96
<span>To find the domain, solve the inequality 4 - x > 0. x < 4. Thus, all numbers less than or equal to 4 represent thedomain for this function. When trying to find the domain and range from a graph, the domain is found by looking at the graph from left to right.</span>
