Answer:
6 < x ≤ 20
Step-by-step explanation:
First, let's use the points (0, 50) and (20, 0) to find the equation of the line.
m = Δy / Δx
m = (0 − 50) / (20 − 0)
m = -2.5
y = -2.5x + 50
Now find the time when y = 35.
35 = -2.5x + 50
-15 = -2.5x
x = 6
So there is less than 35 gallons in the barrel when 6 < x ≤ 20.
What do you need help with
Answer:
C.
Step-by-step explanation:
The next step is to add (1/2 * 8)^2 = 4^2 = 16 to the 8x and subtract 16 from the + 6:
- to give (x^2 + 8x + 16) + 6 - 16 as the next step in the process.
The extreme minimum is +6 - 16 = -10.
3/4x = 2/3
4/3(3/4)x = (2/3)(4/3)
x = 8/9
