The answer to your question is C. -b/a
Part B: It would be 8x+24. You get 4x+12 and double(times 2) it, it would be 8x+24.
Part C: Yes, because the relationship between the ratio would always be proportional.
So, this is kinda similar to the other I helped you with:
<span>So r is the radius of the disk. The area is known and equal to 100Pi; so
100Pi = Pi r2
Now for r: r = 10
Circumference = 2 PI r = 20 Pi
I hope this helped!</span>
Answer:
r = -0.9997
Step-by-step explanation:
A statistics calculator gives the value
r = -0.9997
You can see in the graph below that it represents an excellent negative correlation between x and y.
Every point appears to be exactly on the regression line
