Answer: Its a

Step-by-step explanation:

The value of [tex]x=3+\sqrt{5}[/tex] make the quadratic equation true.

Quadratic equation :

Given equation is,

                     [tex](x-3)^{2}=5[/tex]

We have to solve above quadratic equation.

Expand above equation first,

                 [tex](x-3)^{2}=5\\\\x^{2} +9-6x=5\\\\x^{2} -6x+4=0\\\\x=\frac{6\pm \sqrt{36-16} }{2} \\\\x=3\pm\sqrt{5}[/tex]

Thus, the value of [tex]x=3+\sqrt{5}[/tex] make the quadratic equation true.

point-slope form: y - 5 = (-1/5)(x - 7)

standard form: x + 5y = 7

slope-intercept form: y = (-1/5)x + (7/5)
***note: (-1/5) = -0.2 and (7/5) = 1.4
y-7=-10(x-5) is point slope form.
