nydimaria [60]

Answer:

15 units

Step-by-step explanation:

K(8, 6) and J(-4, -3)

Distance between 2 points

=  \sqrt{(x1 - x2)^{2}  +  {(y1 - y2)}^{2} }

Thus using the formula above,

distance between points J and K

=  \sqrt{ {[8- (-4)]}^{2}  +  {[6- (-3)]}^{2} }  \\  =  \sqrt{ {12}^{2}  +  {9}^{2} }  \\  =  \sqrt{225}  \\  = 15 \: units

Solve the system of equations. <br><br> y=x+5 <br><br> y=-x+7
spin [16.1K]

Answer:

(1,6)

x = 1, y = 6

See attachment for the graph

Step-by-step explanation:

y=x+5  

y=-x+7

Using the elimination process

     y=x+5  

-     y=-x+7

----------------

     0=2x-2

     2=2x

      1=x

      x=1

Substitute x = 1

y = x + 5

y = 1 + 5

y = 6
