What is the slope of a line that is perpendicular to the line<br> y = 2x – 6?

Zolol [24]

Answer:

The slope of a line that is perpendicular to the line y = 2x – 6 is -1/2.

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where

$m$ is the slope

$b$ is the y-intercept

Step 1:

Finding the slope of the given equation

The given equation is

$y = 2x - 6$

comparing with the slope-intercept form of the line equation

The slope of the equation is: m = 2

Step 2:

Determining the slope of the perpendicular line

In Mathematics, a line perpendicular to another line has a slope that is the negative reciprocal of the slope of the other line.

As the slope of the equation is: m = 2

Therefore, the slope of the new perpendicular line:

$-\frac{1}{m}=-\frac{1}{2}$

Hence, the slope of a line that is perpendicular to the line y = 2x – 6 is -1/2.

Important Tip:

The product of the slopes of perpendicular lines is -1.

<u>Verification:</u>

The slope of the given line:

$m_1=2$

The slope of the perpendicular line:

$m_2=-\frac{1}{2}\:\:\:\:$

The product of the slopes is:

$\:m_1\times \:m_2\:=2\times -\frac{1}{2}\:\:=-1$

As the product of the slopes of perpendicular lines is -1, therefore, the lines are perpendicular.

Thus, the slope of a line that is perpendicular to the line y = 2x – 6 is -1/2.

How do I solve this problem?

lara31 [8.8K]

Answer:

x = 12

Step-by-step explanation:

(whole secant) x (external part) = (whole secant) x (external part)

(6+x) *6 = (4+23) * 4

(6+x) *6 = 27*4

6(6+x) = 108

Divide each side by 6

6+x =18

Subtract 6 from each side

6+x-6 =18-6

x = 12

Find three rational numbers between 1 and 0.

Alex73 [517]

Answer:

1/2, 1/4 & 3/4

Step-by-step explanation:

mean of 0 &1 is $\frac{0+1}{2} =\frac{1}{2} \\$

mean of 0 and 1/2 is $(0+\frac{1}{2} )/2=\frac{1}{2} /2=\frac{1}{2} *\frac{1}{2} =\frac{1}{4}$

mean of 1/2 and 1 is $(\frac{1}{2} +1)/2=\frac{3}{2} /2=\frac{3}{2} *\frac{1}{2} =\frac{3}{4}$

So the three rational numbers are 1/2, 1/4 & 3/4

Solve for x: 3 − (2x − 5) < −4(x + 2)

Firdavs [7]

Answer:

A. x < -8 (first option)

Step-by-step explanation:

$3 - (2x - 5) < - 4(x + 2)$

$3 - 2x + 5 < - 4x - 8$

$8 - 2x < - 4x - 8$

$- 2x + 4x < - 8 - 8$

$2x < - 16$

$\boxed{\green{x < - 8}}$
