Answer:

median= 6.5

Step-by-step explanation:

6= 2+5+x+1+x+2+7+9/6

summing up the values

26+2x=36

collecting like terms,

2x=10

divide both sides by 2

x= 5

5+1=6

5+2=7

so the numbers are 2 5 6 7 7 and 9

the median = 6+7/2

= 6.5

What is the slope of a line that is parallel to y = 5x + 3?

Marina86 [1]

Answer:

slope = 5

Step-by-step explanation:

The equation of a lin in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 5x + 3 ← is in slope- intercept form

with slope m = 5

Parallel lines have equal slopes , then

The slope of a line parallel to y = 5x + 3 is 5
