Is this what you need or? Y= 1/4x +3
Answer:
Step-by-step explanation:
What’s the question?
If it’s area then the formula is pi r^2
If it’s the circumference then the 2pi r or pi d
Answer:
7
Step-by-step explanation:
First,
3+2=5
5-8=-3
-3+9=6
6+8=14
14+0=14
14-6=8
8-9=-1
-1+8=7
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
