Answer:
9 weeks
Step-by-step explanation:
So he basically took 14 quizzes in 7 weeks.
14/7 = 2/quizzes per week
18/2 = 9 weeks
I don't know what you mean by unit rates but this is what I got.
Answer: D) Elimination
For example, consider the system of equations below
2x+3y = 9
-2x+6y = 18
Adding straight down will have the x terms (2x and -2x) add to 0x which is just 0. The x terms will go away. In this case, the 2 and -2 are opposite coefficient values for the x terms.
Measures of central tendency are called such because they all find approximately the same "center" of a data set (option B).
<h3>What are measures of central tendency?</h3>
A measure of central tendency attempts to describe a data set by determining the central value of the data set. Measures of central tendency are mean, median and mode
Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number.
Median can be described as the number that occurs in the middle of a set of numbers that are arranged either in ascending or descending order.
Mode refers to a value that appears most frequently in a data set.

The group of points {(0, 1), (0, 5), (2, 6), (3, 3)} is not a function, but the group of points {(1, 4), (2, 7), (3, 1), (5, 7)}
o-na [289]
An x value can only correspond with one value of y in order to be a a function. Although, a y value can correspond with multiple x values. The x=0 in the first set of points corresponds with two different y values: y=1 and y=5. In the second set, none of the x values correspond with multiple y values. If the sets are graphed, the first set of points would pass the vertical line test. If the vertical drawn intersects the graphed segment multiple times, the graph is not a function.
