You need to combine -5x and 5x together and that would give you zero so you need to combine 2y and -8y which would give you -6y so the answer is C. -6y

Ch lists the steps in the correct order to find the median of this data set?
anygoal [31]

Answer:

  1. Put the numbers in order
  2. Cross off the high/low pairs
  3. Add the leftover numbers
  4. Divide the sum by 2

=================================================

Explanation:

The numbers sort to this

16, 18, 23, 24, 29, 30

Cross off the outer most values 16 and 30 to end up with this smaller set

18, 23, 24, 29

Then repeat to get this smaller set

23,24

We add up these numbers and divide the sum by 2

(23+24)/2 = 47/2 = 23.5

The median is 23.5

The last steps of adding and dividing by 2 only works if we have an even number of values in the original set.

A line passes through the two points (-4,6) and (2,-5). Calculate the following parts:
Viktor [21]

A line passes through the two points (-4,6) and (2,-5). 11x +6y - 80 = 0 is the given line equation.

<h3>What is the slope of a line which passes through points ( p,q) and (x,y)?</h3>

Its slope would be:

m = \dfrac{y-q}{x-p}

The slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.

The slope m of the line is given as

m = \dfrac{y-q}{x-p}\\\\ m = \dfrac{-5-6}{2+4}\\\\ m = \dfrac{-11}{6}

The equation of a line is  

( y -y_0) = m (x - x_0)\\\\( y -6) = \dfrac{-11}{6}  (x+4)\\\\6( y -6) = (-11)  (x+4)\\\\6y -36 = (-11x +44)\\\\11x +6y - 80 = 0

Hence, the equation is  11x +6y - 80 = 0
