The correct option is

Step-by-step explanation: We are given to select the correct reason for two line segments to be perpendicular.

We know that

If two line segments are perpendicular, then the product of their slopes is - 1.

Let, m and n represents the slopes of two lines that are perpendicular to each other.

Then, we must have

$m\times n=-1\\\\\\\Rightarrow m=-\dfrac{1}{n}~~~~~\textup{and}~~~~~n=-\dfrac{1}{m}.$

This implies that m is the negative reciprocal of n and n is the negative reciprocal of m.

Thus, the slopes are negative reciprocals.

Option (C) is CORRECT.

Answer from: janiyagoldsmith

If two line segments are perpendicular their slopes are negative reciprocals. Option (C) is correct.

Further explanation:

Given:

The options are as follows,

A. The slope of one is the negative of the slope of the other.

B. Their slopes are reciprocals.

C. Their slopes are negative reciprocals.

D. Their slopes are equal.

Explanation:

Consider the slope of the first line as ${m_1}.$

The slope of the second line is ${m_2}.$

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

$\begin{aligned}{m_1} \times {m_2} &= - 1 \\{m_1} &= \frac{{ - 1}}{{{m_2}}}\\\end{aligned}$

The slopes are negative reciprocals to each other.

If two line segments are perpendicular their slopes are negative reciprocals. Option (C) is correct.

Option (A) is not correct.

Option (B) is not correct.

Option (C) is correct.

Option (D) is not correct.

Answer from: Quest

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
