Vilka [71]3 years ago

Answer:

The given equation which is in two variable is

 ⇒2 x + y =9

As we know that to get a unique solution you need two intersecting lines.

But here only one line is given.

On a single line there lie infinite number of points.

So, for different values of x we get different values of y or different values of y we get different values of x.

So , we can write the above equation as

either ⇒y=9-2 x Or x=9-2 y

I have drawn graph for you.

Thus , there are infinite number of solution of this equation. Like (0,9),(1,7),(2,5),(-2,13),(-1,11),(-3,15)......

The total distance Tracy traveled was 15,000 feet assuming each unit represents 1,000 feet.

<h3>How to calculate the total distance?</h3>

The total distance is the sum of all the distance between stops.

Partial distances:

  • Home to stop 1: 2,000 feet
  • Stop 1 to 2: 4,000 feet
  • Stop 2 to 3: 5,000 feet
  • Stop 3 to 4: 4,000 feet
  • Total distance: 15,000 feet

However, the real distance would be 10.63 units based on the locations in the grid.

  • d=√(0−8)^2+(7−0)^2
  • d=√8^2+7^2
  • d=√64+49
  • d=√113 =10.63 units
