Answer:
f(-1) = -10
f(0) = -6
f(2) = 8
Step-by-step explanation:
As the function says, when x is below 0, the part that we have to use is 7x-3, and when is equal or greater we use 7x-6.
We do so and just replace de values of x in each equation.

For an expression to have a rational equivalent when solved, the denominator should not be equal to 0. If the denominator is equal to zero, the expression becomes indefinite or undetermined. This is the reason for the restriction of the use of x being equal to 3 or -10.
In the given above, we can see that the expression x-3 appears both in the numerator and denominator. Hence, this can be cancelled. We are then left with the expression,
(x + 5) / (x + 10)
Therefore, the answer to this item is letter C.
Answer: 12 hours and 24 Minutes
Step-by-step explanation:
7*60 = 420
810/420 = 1.9285
93- 100 = 53-60
subtract 40 from 93.
1.53*8 = 12.24
Answer: 12 hours and 24 Minutes
If your average speed is 2.05 and your time is the average of .87+.94+.72=0.843 then your answer should be 1.728 because distance= speed x time. I don’t know if this is correct because you didn’t label what the numbers were but I hope this helped you!! :)
I would say no, if you follow the lines on the graph, 12 on the x axis and 5 on the Y axis they are not within the range indicated in gray.
