Answer:
10-
Step-by-step explanation:
Step-by-step explanation:
x -2 -1 2 7
y -6 -6 -2 3
All y are in under root
Answer:
See explanation
Step-by-step explanation:
Given the function f(x) for which

If you want to plot the corresponding points for the inverse of the function f(x), change
into
:

switch x and y

and then change
into
You get

Now plot these points on the coordinate plane (see attached diagram).
Answer is 10(2k+5)
-----------------------------------
Work Shown:
20k+50 = 10*2k + 10*5
20k+50 = 10(2k+5)
Note how we can distribute the 10 back in to check our work
10(2k+5) = 10(2k)+10(5) = 20k+50
so that confirms we have the right answer
Another thing to notice is that 10 is the largest factor that we can pull out of 20k and 50. The value 10 is the GCF (greatest common factor) of 20 and 50.
The green arrow thing is a ray. So, question b. is a ray. So the dot would be B and the arrow would be C.
