Answer:
-3x³ - 4x² + x - 9
Step-by-step explanation:
-5x³ + 2x² + x - 7
- <u>(-2x³ + 6x² + 0 + 2)</u> remember: when you subtract, you 'add the opposite'
-3x³ + (-4x²) + x + (-9)
Answer:
D is the equation of the circle
Answer: It is 2.
Step-by-step explanation:
Make both equation equal to each other and solve for x, as following:
- Add like terms.
- Factor the equation.

Substitute the value of x obtained into any of the original equations to obtain the y-coordinate.
Then, this is:
