Answer:

x²+y²=225

Step-by-step explanation:

r^{2} =9^{2} +12^{2}\\ =81+144\\ =225

Solve the system of equations by substitution - 5x+8y= -86 <br>y=6x-43 ​
n200080 [17]

Answer:

(6 ,-7)

Step-by-step explanation:

- 5x + 8y =  - 86 \\ y = 6x - 43 \\  - 5x =  - 86 - 8y \\ x = 17.2  + 1.6y \\ y = 6(17.2 + 1.6y) - 43 \\ y = 103.2 + 9.6y - 43 \\ 8.6y =  - 60.2 \\ y =  - 7 \\

x = 17.2 + 1.6( - 7) \\ x = 17.2  - 11.2 \\ x = 6
