Hi there!
The correct answer is option B
--------------------------------------------
Since x = -4 is a vertical line(perpendicular to horizontal), so there is no y-intercept and the slope is undefined.
"A vertical
line has undefined slope because all points on the line have the same x-coordinate.
So, the slope is undefined and we also don't have the y - intercept.

Answer:
the answer to 315 / 3 is 105
To solve for s all you have to do is factor the 7 and simplify the rest.
7s-21=21
7s=42
s=6
Answer:
The value of n is 7.
Step-by-step explanation:
For each teen, there are only two possible outcomes. Either they buy soda at least once each week, or they do not. Since they were selected randomly, the teens are independent of each other, which means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
In the binomial distribution, we have that n is the size of the sample. In this question, seven teens are randomly selected, which means that the value of n is 7.
P = 2(L + W)
P = 264
W = 54
264 = 2(L + 54)
264 = 2L + 108
264 - 108 = 2L
156 = 2L
156/2 = L
