Answer:

The answer would be -2 you may look at my work to see how I solved it
Answer:
C
Step-by-step explanation:
This is the shows the constant value on the X-axis
F^-1(x) = sqrt 2(-5+x)/2, - sqrt 2(-5+x)/2
The
slope is the change in y divided by the change in x.
The
slope is the ratio of rise to run.
The
slope is the rate of change of the function at a certain point.
The
slope is the first derivative of a function.
Accordingly, the slope of this line <span>d=420-65t is the coefficient of variable "t" if we consider that d for the dependent variable and t for the independent
Therefore
slope =
- 65</span>
I hope you got
the idea
425 / 50 = 8,5
There you go.
