To solve this question, remember that as per what is given in the problem

X represents the number of hours the batter was used for

Y represents the percent of battery remaining.

The question is simply asking for the percentage of battery remaining after 11 hrs.

Simply plug in 11 for X and solve for y.

If the battery was used for 11 hours, then the value of x we use is 11
Subtitute x with 11 in the equation
y = 100 - 8.9x
y = 100 - 8.9(11)
y = 100 - 97.9
y = 2.1
The remaining power is 2.1%
the answer is option b

PLEASE HELP!!

Answer:

A) $4,905 B) $5,310

Step-by-step explanation:

To get the answer, just simply add the amount by the percentage.

4,500 + 9% = A

For 2 years, just do 9 x 2 = 18 because it's 2 years

4,500 + 18% = B

How do you find the average rate of change through an interval
soldier1979 [14.2K]
In order to find average rate of change over an interval, do the y2-y1/x2-x1. Solve y for x=9 and x= 4
y2 = -3(9-4)^2 + 3 = -72
y1 = -3(4-4)^2 + 3 = 3

Now, x2 matches with y2 and and x1 matches with y1 obviously...
-72 - 3/9 - 4 = -15

What multiplies to -36 but adds to -3
tekilochka [14]
Xy=-36

x+y=-3

x= -36/y

-36/y + y = -3

-36 + y^2 = -3y

y^2 +3y -36 = 0

I think you have to use quadratic formula to find the 2 values of y and then plug in for x
