The answer is D because A and B mean the exact same thing and if A and B are graphed the result is C so the only logical answer left is D
Well...what are the expressions and phrases???
Answer: 20 = 5 × n ; n = 4
How do we know?
If the blue jar has 20 marbles, and the blue jar has 5 times as many as the red jar, and n is how many marbles are in the red jar then we can use this equation:
n × 5 = 20
So for the first portion of your question the answer would be: 20 = 5 × n
Now we have to solve for n:
20/5 = n
4 = n
So the answer to your second part would be: n = 4

Step-by-step explanation:
Answer: 5
----------------------------------------------------------
On the curve, the highest point has a y coordinate of y = 6
The lowest point on the curve has a y coordinate of y = -4
Subtracting the y values gets us: 6 - (-4) = 6 + 4 = 10
Cut that result in half: 10/2 = 5
The amplitude is 5. This is the vertical distance from the midline (y = 1) to either the highest point or the lowest point.
