Answer:
We conclude that the rule for the table in terms of x and y is:
Step-by-step explanation:
The table indicates that there is constant change in the x and y values, meaning the table represents the linear function the graph of which would be a straight line.
We know the slope-intercept form of the line equation
y = mx+b
where m is the slope and b is the y-intercept.
Taking two points
Finding the slope between (-2, -4) and (-1, -1)
We know that the y-intercept can be determined by setting x = 0 and finding the corresponding y-value.
Taking another point (0, 2) from the table.
It means at x = 0, y = 2.
Thus, the y-intercept b = 2
Using the slope-intercept form of the linear line function
y = mx+b
substituting m = 3 and b = 2
y = 3x+2
Therefore, we conclude that the rule for the table in terms of x and y is:
Answer:
every other student who enters the school
Step-by-step explanation:
It is given that the middle school students have an average height of 5.25 feet. The students belongs to Seton Grove School.
It means that every student who comes to this school or enters the school has a height that is around 5 feet or more.
Thus we can say that every other student who enters the school has a average height of 5.25 feet.
This sample makes the generalization about the heights of the school students valid.
Answer: The population is all US workers. The sample is adults who respond to the survey.
Step-by-step explanation: The population is the intended group that the question is about, all U.S. workers.
The sample is a small portion if that group, as it would be practically impossible to get data from everyone,
This sample is the adults who responded to this sutvey.
The sample might not be an accurate cross section of all workers, depending on how the website ensures that it includes appropriate segments of urban, suburban, and rural dwellers, from various regions of the country, and from different economic groups.
Answer:
5*(a + 6)
Step-by-step explanation:
5a + 30 = 5*(a + 6)
A function is a relationship where each x-value is paired with exactly one y-value.
When looking at a graph, you want to ask yourself, "Can I find any two points on this graph that have the same x-value?"
I can see with x=8 that there would be two points on that graph with an x-value of 8, making this not a function.
People call this test "the vertical line test" because any vertical line really represents a single x-value. If any vertical line hits the graph more than once, the graph cannot be a function, because that value of x has more than one y-value.
