Answer:

Given :

→x-y=12

→xy= 3²

=9

Equation formed:

{(x - y)}^{2}  =  {x}^{2}  +  {y}^{2}  - 2xy

Step by step explanation:

{(12)}^{2}  =  {x}^{2}  +  {y}^{2}  - 2 \times 9 \\  144   + 18 =  {x}^{2}  +  {y}^{2}  \\  = 162

Is (2, 6) a solution to this system of equations?<br> y = -x + 8<br> y = 5x - 4<br> yes<br> no
Alexxx [7]

Answer:

Yes

Step-by-step explanation:

To see is (2, 6) is a system, we can plug it into the system to check if it gives us true statements:

6 = -2+8

6 = 6

6 = 5(2)-4

6 = 10-4

6 = 6

Both of the equations are true, therefore (2, 6) is a solution to this system.
