Answer:

The root of x = -2 + √2

Step-by-step explanation:

Step(i):-

Given $\sqrt{2x^{2} } + x +\sqrt{2} = 0$

⇒ $\sqrt{2} } ( x^2 ) ^{\frac{1}{2} } + x +\sqrt{2} = 0$

⇒ $\sqrt{2}x + x +\sqrt{2} = 0$

⇒ $(\sqrt{2} + 1) x = - \sqrt{2}$

$x = \frac{-\sqrt{2} }{(\sqrt{2} + 1)}$

Step(ii):-

Rationalizing

$x = \frac{-\sqrt{2} }{(\sqrt{2} + 1)} X \frac{(\sqrt{2} - 1)}{(\sqrt{2} - 1)}$

Apply ( a-b ) ( a+b) = a²-b²

$x = \frac{-\sqrt{2}(\sqrt{2} -1) }{(\sqrt{2})^{2} - 1^{2} )} = \frac{-(2-\sqrt{2} }{2-1}$

The root of x = -2 + √2

Perpendicular to the line 2x-5y=-11; passes through (7,5)

Westkost [7]

Answer:

$y=-\frac{5}{2}x+\frac{45}{2}$

Step-by-step explanation:

The slope intercept form of a line is given as:

y = mx + c

Where m is the slope and c is the y-intercept

Let's rearrange the equation given in this form:

2x - 5y = -11

5y = 2x + 11

y = 2/5 x + 11/5

So the slope is 2/5

Slope of line that is perpendicular to this is the "negative reciprocal" of this slope. Which means the slope of perpendicular line would be -5/2

Thus, equation would become: y = -5/2x + c

Now we need to find c. For this we plug in 7 into x and 5 into y and solve for c [(7,5) is the point given]. Thus,

$y=-\frac{5}{2}x+c\\5=-\frac{5}{2}(7)+c\\5=-\frac{35}{2}+c\\c=5+\frac{35}{2}\\c=\frac{45}{2}$

Thus, the equation of perpendicular line is:

$y=-\frac{5}{2}x+\frac{45}{2}$
