If you draw out a coordinate plane you will see that they , on their Y access, are both nine witch means that they a horizontal line so all you have to do is subtract the x access witch is 3.

hope this helped

Given the points (2.1) and (-4,-5) Find the point-slope form of the line.
Inessa05 [86]

Answer:   y = x - 1

<u>Step-by-step explanation:</u>

Use the Point-Slope form: y - y₁ = m(x - x₁)    where

  • (x₁ , y₁) is any point on the line
  • m is the slope of the line

\text{Slope (m)}=\dfrac{y_2-y_1}{x_2-x_1}

Let (x₁, y₁) = (2, 1) and (x₂, y₂) = (-4, -5)

m=\dfrac{-5-1}{-4-2}\quad =\dfrac{-6}{-6}\quad =1

Point-Slope form:   y - 1 = 1(x - 2)

                               y - 1 =  x - 2      <em>distributed 1 to (x - 2)</em>

                                    y = x - 1       <em>added 1 to both sides</em>

The cost of packing a box of chocolates is given by x2, where x is the number of chocolates (a box can never have fewer than 3 c
Levart [38]
 <span>For a box with x chocolates, the cost of packaging is C(x) = x^2 and the 
weight is W(x) = x + 2. Thus the cost per unit weight is C(x) / W(x) = x^2 / (x + 2)</span>

A bag contains 6 blue marbles 10 red marbles and 9 green marbles. If 2 marbles are drawn at random without replacement what is t
umka2103 [35]

Answer:

P(1 and 2 are green) = 3/25

Step-by-step explanation:

We need to know the total number of marbles

6 Blue + 10 red + 9 green = 25 marbles

P ( 1st marble is green) = green/ total

                                       = 9/25

Since we don't put it back, there are  

6 Blue + 10 red + 8 green = 24 marbles

P ( 2st marble is green) = green/ total

                                       = 8/24  = 1/3

P(1 and 2 are green) = P(1st green) * P(2nd green)

                                  = 9/25 * 1/3

                                   = 3/25

How to round to the naerst 10?
Blababa [14]
So, say your # was 6,234,578. you would go to the seven and look to the number next to in, so 8, and if the neighbor is 5 or bigger, you make the number, in this case a 7 an 8. Last, you make all the other #s after the one you rounded 0. So the answer would be:

6,234,570.0
