Option D: No, the distance from (0,0) to (2, \sqrt{6}) is not 3 units.

Explanation:

From the figure, we can see that the radius of the circle is 3 units.

We need to determine that the point (2, \sqrt{6}) lie on the circle.

This can be determined by substituting the coordinate (0,0) and (2, \sqrt{6}) in the distance formula,

d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}

Thus, we get,

d=\sqrt{\left(\sqrt{6} -0\right)^{2}+\left(2-0\right)^{2}}

Simplifying, we have,

d=\sqrt{\left(\sqrt{6} )^{2}+\left(2)^{2}}

d=\sqrt{6+4}

d=\sqrt{10}

d=3.2

Thus, the distance from (0,0) to (2, \sqrt{6}) is 3.2 units.

Hence, the point (2, \sqrt{6}) does not lie on the circle because the distance is more than the radius 3 units.

Therefore, the distance from (0,0) to (2, \sqrt{6}) is not 3 units.

Thus, Option D is the correct answer.

Which graph represents the solution to the given system? y = –2x + 5 and y = 3x – 2
DaniilM [7]
Y = -2x + 5        y =3x - 2
Since both equations are equal to 'y' you can set them equal to each other to solve.
-2x + 5 = 3x - 2             Subtract 3x from both sides
-5x + 5 = -2                  Subtract 5 from both sides
-5x = -7                        Divide -5 on both sides
x = 7/5
Plug 7/5 back in for x and solve for y.
y = -2(7/5) + 5
y = (-14/5) + (25/5)
y = 11/5
(7/5, 11/5) OR (1.4, 2.2)
