Answer:
y = 3x - 9
Step-by-step explanation:
Using point slope form equation
y - y1 = m(x - x1)
Given
Point = ( 6 , 9)
Slope = 3
x1 = 6
y1 = 9
y - 9 = 3(x - 6)
Using a slope intercept form equation
y = mx + c
Open the bracket
y - 9 = 3( x - 6)
y - 9 = 3x - 18
y = 3x - 18 + 9
y = 3x - 9
The equation of the line is
y = 3x - 9
12.6 repeating would be 12.666666666666666666..... That's larger then 12.63 because the number in the hundredths place is larger 6 is larger than 3
All this is a unit conversion really, initially you'll need to put the 460.28 oz over the 12.44 hours. Your expression should read as 460.28 oz/12.44 hr, next simply divide and you will have your answer of 37 oz/hr
You basically just have to do . . .
257/54
4.759 . . .
≈ 4.76 hours
Answer: 4.76 hours
