x = 25 / 3squared + 5
2x + 52 = 7 2x + 25 = 7 2x = 7 - 25 2x = -18 x = -18/2 x = -9
X (x - 25) So X = 0 Or X = +25
They are +/- 5*sqrt(2)
x=-.25.
x = 25 / 3squared + 5
5.
It is the Cartesian equation of an ellipse.
2.5 + 3.4 Pythagorean Theorem?
2x + 52 = 7 2x + 25 = 7 2x = 7 - 25 2x = -18 x = -18/2 x = -9
X (x - 25) So X = 0 Or X = +25
They are +/- 5*sqrt(2)
x=-.25.
-5x2 = -75 x2 = 25 x = ±sqrt( 25 ) x = ±___
25 squared plus 49 squared is equal to 3,026.
The centre is (-5, 3)
since y = 3x+1 we have y squared =(3x+1) squared x^2 + y^2 = 25 x^2 + (3x+1)^2=25 x^2 + 9x^2+ 6x+1 = 25 10x^2 + 6x + 1 = 25 10x^2 + 6x -24 = 0 solve x from quadratic formula x = 1.28 y = 3x + 1 = 4.83
