Which is not a function
A function is of the form
Assume a function is:
In simple terms:
For an ordered pair to be regarded as a function, no x value must be repeated
Analyzing the options:
1.
This is a function because none of the x values (-3, 8, 0 and -9) appeared more than once
2.
This is a function because none of the x values (5, -3, 0 and -9) appeared more than once
3.
This is a function because none of the x values (9, -5, 5 and 6) appeared more than once
4.
This is not a function because one of the x values (2) appeared more than once.
i.e.
and
Answer: x + 7y = 12
Explanation:
The question is: "I<span>ndicate in standard form the equation of the line passing through the given points. E(-2, 2), F(5, 1)"
</span>
1) The standard form of the equation of the line passing through two points is:
Ax + By = C
2) You can find the equation of al line given two points in a two stages process:
i) Find the slope:
slope = m = [y₂ - y₁] / [ x₂ - x₁] = [1 - 2] / [5 - (-2) ] = - 1 / 7
ii) set the point slope equation:
y - y₁ = m [x - x₁]
y - 1 = (-1/7) (x - 5) ⇒ 7 ( y - 1) = - (x - 5)
⇒ 7y - 7 = - x + 5 ⇒ x + 7y = 5 + 7
⇒ x + 7y = 12

Um..since it twelve times at many bars then you do 54*12 which equals 648. 594 more
Sorry this took so long... You can also use your calculator by pressing 10 then <math>,<prob>,<nCr> then 6
Answer:
D.) The mean may change, but the median will not change.
Step-by-step explanation:
By adding two new values to the existing dataset ; this two values are extreme values as described in the dataset.;
As the warmer will be the new minimum and the colder the new maximum .
The median value being the midpoint of the dataset when arranged in order will definitely not be affected by these new additions are at the beginning and end of the data set. Hence, the previous median points will Also be the new median points.
As for the mean, it has to do with calculation the average value, despite the number being at the extreme, the new points may take up any value and hence will affect the new sum and ultimately the obtained average.
Therefore,The mean may change, but the median will not change.
