The value of h(3) is 120 ⇒ B
Step-by-step explanation:
To find the value of f(x) at x = a, do that
- Substitute x by a
- Find the value of f(a)
∵ 
- To find h(3) substitute x by 3
∴ 
∵ 
= 81
∵ (3)² = 9
- Substitute them in the function above
∴ h(3) = 2(81) - 4(9) - 2(3)
∴ h(3) = 162 - 36 - 6
∴ h(3) = 120
The value of h(3) is 120

Step-by-step explanation:
Downers grove = 5 inches of snow + 6 inches every hour
= 5 + 6h
Woodridge = 13 inches + 2 inches every hour
= 13 + 2h
Where,
h = number of hours
In how many hours will the snowfall of the towns be equal?
Equate the snow falls of the towns
Downers grove = Woodridge
5 + 6h = 13 + 2h
Collect like terms
5 - 13 = 2h - 6h
8 = 4h
Divide both sides by 4
h = 8 / 4
= 2
h = 2 hours
The snowfall of the towns will be equal in 2 hours
Answer:
The copy machine makes 87.5 copies in one minute.
Step-by-step explanation:
Set up an equation to divide 4 into 350. This is because in order to know how many copies is being made in 1 minute, you need to determine the rate of copies per minute.
350 divided by 4 is 87.5.
