Answer:
a) -3 gallons per hour
b) y = -3x +14
Step-by-step explanation:
Rate of change is computed by dividing the amount of change by the interval over which it occurred.
<h3>a)</h3>
Here the amount of gas decreased from 14 to 2 gallons, so a decrease of 14-2 = 12 gallons. That occurred over a 4-hour period, so the rate of change is (-12 gallons)/(4 hours) = -3 gallons/hour.
__
<h3>b)</h3>
The initial amount was 14 gallons, so the equation for the line describing remaining gas will be ...
y = -3x +14 . . . . gas in the tank after x hours
3 2/3
multiply the whole number with the denominator
3*3=9
Add 9 with the numerator
numerator is 2
9+2=11
Answer:
11/3
The answer to the corresponding part is <Y
Step-by-step explanation:
First of all, use substitution to find slope
(1) = m(3) - 2
3 = m3
m = 1
With both the slope and y int, you can write it in y int form
y = 1x - 2
Convert that to standard form
-x + y = -2
