A company performed power tests on a set of batteries of the same type. The company 10 determined that the equation y = 100 - 8.
alexgriva [62]
For this case we have the following equation:
 y = 100 - 8.9x
 Where,
 x = the number of hours of use
 For 11 hours of use we have x = 11.
 Substituting:
 y = 100 - 8.9 * (11)
 y = 2.1%
 Answer:
 
the best prediction of the percent of remaining power for a battery after 11 hours of use is:
 
y = 2.1%

Find the slope intercept form of the line passing through (3,9) and (0,3).
ANEK [815]

Answer:

y = 2x +3

Step-by-step explanation:

To find the slope we do (Y1 - Y2)/(X1-X2) aka rise over run

So, m = (9 - 3) / (3 - 0)

m = 2

Now we have y = 2x +b

Notice one of our points is (0,3)

Since the x value of that point is 0, it is the y intercept.

In the slope intercept form b = y-intercept

Therefore b = 3

So, y = 2x + 3

That's your answer because if the number is 5 or larger, you round up. Because 6 is larger than 5, it rounds up to zero and then the 3 becomes a 4.
