A
It is a first degree polynomial (aka linear because its highest power is 1) and it has two terms (2x and 8)
It does not have eight terms and is not a monomial (one term ie 3x^2)
Answer:

Step-by-step explanation:
-Probability is the likelihood of an event occurring.
-The total number of events is:

-The total number of blue events is:

#Probability of a blue is thus calculated as:

Hence, the probability of choosing a blue marble at random is 37.5%
Answer:
B.
Step-by-step explanation:
You pay a one time fee of 18 dollars and then 2 dollars per ride.
The expression for that is 18+2r where r represents the number of rides and the output of (18+2r) is amount you spend.
f(r)=2r+18 when compared to f(x)=mx+b where m is slope and b is y-intercept
you should see that the slope is $2 per ride.
B. is the option that says this.
