Step-by-step explanation:

equation of the line passing through two points

x-x1/x2-x1=y-y1/y2-y1

x-(-8)/1-(-8)=y-2/9-2

x+8/9=y-2/7

7x+56=9y-18

9y=7x+56+18

y=7/9x+74/9

y=mx+b m is the slope

so m=7/9

there is a short way showing slope shown in the picture

500ft of lights to hang the width of the room is 70ft what is the length of room if she can hang all the lights so that they go
eduard

Answer:

180 ft

Step-by-step explanation:

We are working to find the perimeter here. Let x represent the length of the room.

We know that the formula to find the perimeter of something is 2L + 2W = P. Here, we know the required perimeter and the width of the room.

Our equation is now: 2x + 2(70) = 500

Now we have to find x, we'll start by multiplying 70 by 2.

2x + 140 = 500

Now we can solve for x:

Subtract 140 from both sides

2x = 360

x = 180

The length of this room is 180 ft.

2(180) + 140 = 500

360 + 140 = 500

Answers:

  1. Function
  2. Not a function
  3. Function
  4. Not a function

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

Explanation:

If x repeats itself, then we don't have a function. For instance, relation 2 has the x value -4 show up twice. That input leads to multiple outputs which is why we don't have a function. Relation 4 is a similar story (this time the input 'u' shows up twice).

Relations 1 and 3 don't have this issue, so they are functions.
