What method would you choose to solve the

Mekhanik [1.2K]

Answer:

see explanation

Step-by-step explanation:

2x² - 7 = 9 ( add 7 to both sides )

2x² = 16 ( divide both sides by 2 )

x² = 8 ( take square root of both sides )

x = ± $\sqrt{8}$ ← exact values

This method is useful when there are only numeric values to deal with

A walking path across a park is represented by the equation y=-4x+10. A new path will be built perpendicular to this path. The p

Lera25 [3.4K]

Given:

The equation of a line is

$y=-4x+10$

A perpendicular line on the given line passes through the point (4,-6).

To find:

The equation of the perpendicular line.

Solution:

We have,

$y=-4x+10$

On comparing this equation with slope intercept form $y=mx+b$ , we get

$m=-4$

So, the slope of the given line is -4.

We know that the product of slopes of two perpendicular lines is always -1.

$m\times m_1=-1$

$(-4)\times m_1=-1$

$m_1=\dfrac{-1}{-4}$

$m_1=\dfrac{1}{4}$

The slope of the required line is $\dfrac{1}{4}$ and it passes through the point (4,-6). So, the equation of the line is

$y-y_1=m_1(x-x_1)$

$y-(-6)=\dfrac{1}{4}(x-4)$

$y+6=\dfrac{1}{4}x-1$

$y=\dfrac{1}{4}x-1-6$

$y=\dfrac{1}{4}x-7$

Therefore, the correct option is B.
