The points (-5, 5) and (5, r) lle on a line with slope -3. Find the missing coordinate r.

Mathematics

Answer:

r = -25

Step-by-step explanation:

slope is change in "y" over change in "x"

so whatever your change in "x" is between the two points, the change in "y" needs to be in proportion to the slope of -3.

Here the change in "x" is +10, and to make the proportion of the slope equal to -3, the change in "y" needs to be -30.

Starting from the "y" coordinate of 5, a change in "y" of -30 will give you r = -25

So the two points are (-5, 5) and (5, -25)

A. in terms of the number of marked elk, what is the relative frequency of male elk, female elk, adult elk, and baby elk? write
mash [69]

The relative frequency of the marked elks are:

  • Male Elk  = 7/30
  • Female Elk = 4/15
  • Adult Elk= 173/450
  • Baby Elk = 26/22

<h3>How to determine the relative frequency?</h3>

From the complete question, we have:

  • Male = 105
  • Female = 120
  • Adult =  173
  • Baby = 52
  • Total = 450

The relative frequency of each is then calculated as:

Male Elk = 105/450

Male Elk  = 7/30

Female Elk = 120/450

Female Elk = 4/15

Adult Elk= 173/450

Baby Elk = 52/450

Baby Elk = 26/22

<h3>The number of Elks in the park</h3>

Using the data in (a), we can conclude that:

There are 105 male, 120 female, 173 adult, and 26 baby in the park

Answer:

y=-5x

Step-by-step explanation:

this is because slope intercept form is y=mx+b

if m= -5 and b=0 the answer would be

y=-5x+0

simplified it would be

y=-5x
