Answers
Answer:
y=-2x+6
Step-by-step explanation:
So you know the perpendicular gradient is -2 so the equation so far is y=-2x+?
Find the midpoint of AB which is:
(3,0)
Using this, plug it into the equation you've formed:
0= -6 + ?
? = 6
So the equation of the perpendicular line is y=-2x+6

That’s the answer
The mean height decreases because of the outlier, The median stays the same and the range increases because of the outlier.
What is an Outlier in a Dataset?Outlier in a data set is simply the extremely low data point or an extremely high data point compared to other points in the dataset.
It will stand out from the other values in the dataset.
Given a dot plot which represents the height in inches of the Deep Purple Gymnastics Team members.
Only mean and range is affected by the outlier, median will not, since the middle value of the data set remains the same even if the end values are changed.
Here outlier is at the lowest end, which is 60.
Mean is the average of the data points. Since the outlier is at the low end, mean decreases.
Median stays the same.
Range is the difference of maximum and the minimum value. Range increases since the minimum value is lower.
Hence the mean decreases, median stays the same and range increases.

Find the value f x,
[tex]7x-\left(x-12\right)=32-4x[/tex]
Answers
Answer:
x = 2.
Step-by-step explanation:
7x - (x - 12) = 32 - 4x Distributing the negative over the parentheses:-
7x - x + 12 = 32 - 4x Bringing like terms together:-
7x - x + 4x = 32 - 12 Simpifying:
10x = 20
x = 2.
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
In order to solve for the variable [tex]x[/tex], simply move all terms with the variable to one side and all constants to the other. [tex]7x-(x-12)=32-4x[/tex] => [tex]7x-x+12=32-4x[/tex] => [tex]6x+12=32-4x[/tex] => [tex]10x=20[/tex] => [tex]x=2[/tex].
You can check this answer by plugging it back into the equation as a substitute for the variable. [tex]7(2)-(2-12)=32-4(8)[/tex] => [tex]14-(-10)=32-8[/tex] => [tex]24=24[/tex], since the equation is true, this proves that x = 2 is the correct answer.
Aisha is ordering a taxi from an online taxi service. She has to pay a flat charge just to
order the taxi, and then has to pay per mile, depending on how far she travels. She
wrote an equation to represent her total cost, y = 2.8x + 2, where y represents the
total cost in dollars and cents, and a represents the number of miles she travels,
What could the number 2 represent in the equation?
Answers
Answer:
The flat charge
Step-by-step explanation:
The number 2 could represent the flat charge in the equation because a flat charge never changes. In the equation, the 2 (y-intercept) is the only term that does not change. The value of 2.8x depends on what the value of x is, and the value of y depends on what the value of 2.8x + 2 is. Therefore, 2 could represent the flat charge in the equation.
At an internet cafe, there is a flat fee to log into a computer and an additional charge for each minute on the computer. The fee (in dollars) for using Mac for x minutes is given by M=0. 5+0. 07 x
