Answer:
f(x) = -1/3x +23/3
Step-by-step explanation:
You can use the linear regression function of a graphing calculator or spreadsheet to show you the equation of the line through these points:
f(x) = -1/3x +23/3
__
Approaching this in the usual way, we recognize we have points ...
(-1, 8) and (5, 6)
The slope of the line through those points is ...
m = (y2 -y1)/(x2 -x1)
m = (6 -8)/(5 -(-1)) = -2/6 = -1/3
Then the point-slope equation of the line is ...
y - 8 = -1/3(x +1)
Adding 8 gives us a form we can use for a function definition:
f(x) = -1/3(x +1) +8
f(x) = -1/3x +7 2/3
The answer you are looking for is 9/11.
When dividing fractions, you multiply the first value by the inverse of the second value. The inverse is found by simply flipping the numbers of the last fraction. So, the inverse is 9/4. Then, multiply 4/11 and 9/4 to get 36/44. 36/44 simplified (divided by 4/4) is 9/11. Thus making 9/11 the answer.
I hope this helps.
Answer:
7 hours
Step-by-step explanation:
25.75(total cost of the rental)
-10.00 (cost of initially renting the bike)
----------------
15.75$ (cost of hourly fees)
15.75/2.25(hourly rate) = 7
Answer:
divide
Step-by-step explanation:
maybe this will help you because the answer sound like divide ok maybe .
The pattern is multiplying the number by -2. So it would continue on as 96, -192, 384, and so on.
