The lines represented by the equations 20y-24x=-20y and 5y-6x=-5 are a) perpendicular
b) the same line
c) neither parallel nor perpendicular
d) parallel

The answer is perpendicular

Step-by-step explanation:

convert the two equations into slope-intercept form

y=7/5x - 1

y=6/5x -1

Then, put it in the graph and you'll get lines intersecting at the same point which is the y-intercept.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
