ANSWER
The solution is ![(-1,9)](https://tex.z-dn.net/?f=%28-1%2C9%29)
EXPLANATION
We want to solve the simultaneous equations
![y=-3x+6---(1)](https://tex.z-dn.net/?f=y%3D-3x%2B6---%281%29)
and
.
We substitute equation (2) in to equation (1), to obtain
![9=-3x+6](https://tex.z-dn.net/?f=9%3D-3x%2B6)
This has now become a linear equation in a single variable
.
We solve for x by grouping like terms.
![9-6=-3x](https://tex.z-dn.net/?f=9-6%3D-3x)
![3=-3x](https://tex.z-dn.net/?f=3%3D-3x)
We divide through by negative 3 to get;
.
Hence, the solution is ![(-1,9)](https://tex.z-dn.net/?f=%28-1%2C9%29)
Answer:
Step-by-step explanation:
<u>Use intersecting chords theorem:</u>
- 5(5x + 2) = 10(6)
- 5x + 2 = 12
- 5x = 10
- x = 2
