Answer: y=x
The slope of the perpendicular line is the opposite reciprocal. So you do -(-1/1) which equals 1. So now we have y=x+b. Plug (3,3) into this and you get 3=3+b. So b=0 and the equation is y=x

I need help with a problem with solving by square roots in quadratic equation.
Readme [11.4K]

To solve for x, first, we add 3 to the given equation:

\begin{gathered} 2(x+5)^2-3+3=44+3, \\ 2(x+5)^2=47. \end{gathered}

Dividing by 2, we get:

(x+5)^2=\frac{47}{2}.

Therefore:

x+5=\pm\sqrt{\frac{47}{2}}.

Finally, subtracting 5 we get:

x=\pm\sqrt{\frac{47}{2}}-5.

Answer:

x=\operatorname{\pm}\sqrt{\frac{47}{2}}-5.

The sum<br> of three consecutive integers is - 126. What are the integers?
Leno4ka [110]
Let the three consecutive integers be x , x+1 ,x+2
Given, sum of three consecutive integers = -126
x +x+1+ x+2 = -126
3x +3 = -126
3x = -126 -3
3x = -129
x = -129/3
x = - 43
x +1 = -42
