This is for A part A: It shows that the least amount is 37.5 minutes
It shows the most amount of time is 60 minutes
One thing it does not show is how many students where in the class.
For number 9 it's x+8= 14 and 7x=21
For number 10 the answer is that Beth is correct because the only number that could be replaced for x would be 2. There is no number besides 2 that you could put in the equation x+3=5 to get the answer 5.

Answer:
Step-by-step explanation:
y(x) and f(x) are similar in meaning; they both state that the dependent variable is a function of the independent variable x.
f(x) = 5x = y(x).
Subtract -6 from both sides
3x^2 + 17x + 4 - (-6) = -6 - (-6)
3x^2 + 17x + 10 = 0
factor left side of equation
(3x+2)(x+5)=0
set factors to 0
x = -2/3 OR x = -5
I would go with -5
