Please explain :) 2x + 12 <img src="https://tex.z-dn.net/?f=%20%5Cgeq%20" id="TexFormula1" title=" \geq " alt=" \geq " align="ab

Semmy [17]

$2x+12 \geq 6 \ \ \ |\hbox{subtract 12 from both sides} \\
2x \geq -6 \ \ \ |\hbox{divide both sides by 2} \\
x \geq -3$

Which lines are perpendicular?

makkiz [27]

Given:

Line A: $y=\frac{1}{2} x+2$

Line B: $y=\frac{-1}{2} x+7$

Line C: $y=2 x+4$

Line D: $y=\frac{1}{2} x+\frac{5}{4}$

To find:

Which lines are perpendicular

Solution:

General equation of a line:

y = mx + c

where m is the slope and c is the y-intercept.

Slope of line A = $\frac{1}{2}$

Slope of line B = $\frac{-1}{2}$

Slope of line C = 2

Slope of line D = $\frac{1}{2}$

<em>Two lines are perpendicular if their slopes are negative reciprocal of one another.</em>

$$\Rightarrow m_1=\frac{-1}{m_2}$

$$\frac{-1}{2}=-(-2)=2$

Negative reciprocal of $\frac{-1}{2}$ is 2.

Therefore line B and line C are perpendicular lines.
