Question

X^2+y^2=25 Y= 2x - 5
What are the x coordinates

Answer 1

(0, -5) and (4, 3)

Explanation:

I assume you're looking for the coordinates of the intersections, if any.

Solve by substitution:

x² + (2x − 5)² = 25

x² + 4x² − 20x + 25 = 25

5x² − 20x = 0

5x (x − 4) = 0

x = 0 or 4

So the coordinates are (0, -5) and (4, 3).
