This can be solve by first solving the proportionality constant
Number electic outlets rewired is directly proportional to
time spent
4 = (1 ½)a
Let be the proportionality constant
A = 8/3
O = (8/3)(7.5)
o = 20 outlets will jamal rewired if he works for 7.5 hrs

Answer:
(-10,-7)
Step-by-step explanation:
Lets start with the equation y>-3x+7
Which of these are solutions?
(5,-5) - yes
(10,-8) - yes
(5,-6) - yes
(-10,-7) - no
Now lets do the equation y<4/5x-2
Which of these are solutions?
(5,-5) - yes
(10,-8) - yes
(5,-6) - yes
(-10,-7) - no
So, the point (-10,-7) is not a solution to the system of equations.
Answer:
The value of h(f(x)) is x.
Step-by-step explanation:
We have to find the value of h(f(x))
This problem can be solved by using inverse trigonometric concept
Here the functions in the given problem g and h are the inverse function
Let us assume
If g(h(x))=x for all x in domain of h
Similarly,
h(g(x))=x for all x in domain of h
So from the given we have h(x) as the inverse of f(x)
Thus from the definition of the inverse function we know that
h(f(x))=x
Hence the value of h(f(x))=x
