Ответ:
There is one solution
Step-by-step explanation:
15x+11=8x
Subtract 15x from each side
15x-15x +11 = 8x-15x
11 = -7x
Divide by -7
11/-7 = -7x/-7
-11/7 =x

Step-by-step explanation:
distance formula is![} d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}](/tpl/images/1245/9483/741e1.png)
Distance (d) =√(9 - 1)2 + (9 - -5)2
=√(8)2 + (14)2
=√260
=2√65
