Answer:

\boxed{r = -20}

Step-by-step explanation:

=  >  - 7r =  - 8r - 20 \\  \\  =  >  - 7r + 8r =  - 20 \\  \\  =  > 8r - 7r =  - 20 \\  \\  =  > r =  - 20

Evaluate the piecewise-defined function for the indicated values. I’m just unsure of how to solve when the value isn’t given dir
Fantom [35]

The value of the function at t=0 is 9 , 6<x<7 is -t+5, 1<n<2 is 9, for m^{2} +1 is 9.

Given function which is 9 for 0 to 5 , -t+5 for 5 to 8 and \sqrt{t-1} for 8<t<11.

A) We have to find the function at t=0 which is 9 because it lies between 0<=t<5.

B) In this we have to find the value of the function when x=t lies between 6 and 7. is -t+5.

C) In this we have to find the value of Q(n) when n lies between 1 and 2 and the value becomes 9 because it lies between 0 and 5.

D) In this we have to find the function at m^{2} +1 when m belongs to \sqrt{7} and \sqrt{10} the value of m lies between 2 and 4 and the value of m square +1 lies between 3 and 5. Hence the value of function at m square plus one is 9.

Which of the functions below could have created this graph?
Yuri [45]
It's A), because if the highest exponential would've been uneven, the graph would go up, then down, but as you can see it kinda resembles a parabola, making it one out of A) and B)
as you can see, the graph crosses the system at (0/0), so it can't be C), due to it's constant at the end, being "+1"
so it's A)
