Total checkers = 2 + 6 = 8
P(black, then red) = (6/8)(2/7) = 3/14
Answer: 3/14
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
Answer:
Simple interest is calculated based only on the principal balance, whereas compound interest is calculated based on the principal balance and the accumulated interest from the previous periods. This means compound interest will make the amount owed grow at a much faster rate than simple interest.
Hope this helps!!!
Step-by-step explanation:
Answer:
4x + 14
Step-by-step explanation:
So first you would 2 times 2x to get 4x and then 2 times seven to get 14. So you would get 4x plus 14.
