Which choices are correct when determining the distance between −56 and 69?
Gnesinka [82]

The choices that are correct when determining the distance between −56 and 69 are |-56 - 69| and 125 units

<h3>How to determine the choices that are correct when determining the distance between −56 and 69?</h3>

The endpoints are given as

−56 and 69

The distance between the endpoints is calculated using

Distance = |Difference between  endpoints|

So, we have:

Distance = |-56 - 69|

Evaluate

Distance = 125

Hence, the choices that are correct when determining the distance between −56 and 69 are |-56 - 69| and 125 units

PLEASE HELP ME EVERYONE HAS GOTTEN THIS WRONG ITS GONNA SUBMIT IN 15 MIN PLS HELP THANK YOU

Answer:

x=4.8

This here you use Pythagorean Theorem.

Step-by-step explanation:

a^2+b^2=c^2

The longest side is c. And the two legs are a and b.

So it'd be 11^2+x^2=12^2

121+x^2=144

Subtract 121 from both sides.

x^2=23

Then take the √ of x^2 and 23

So √x^2=√23

x=4.8

Hope this helps

NEED HELP NOW!! Will give 20 extra PTS to the best answer

To find the value of y, you need to plug a value into the x variable, in this case -8.

     4x + 9y = -14     Substitute -8 for x
4 (-8) + 9y = -14     Multiply
   -32 + 9y = -14     Start isolating the variable by adding 32 to both sides
            9y = 18      Divide both sides by 9
              y = 2

When x = -8, y = 2
