Perpendicular lines in equations are negative reciprocals of each other. If you multiply two slopes together and they equal -1, they are perpendicular.
3 * -1/3 = -1 so the slope is -1/3.

Equations that have the same slope are parallel. If another line had a slope = to 3, then the line would be parallel to y=3x-1

there are a 100 student in a garde 79 students has honors what deciaml best represents the amount that the student honors
gogolik [260]

There are 100 students. In the 100 students, 79 of them have honors. To find the decimal form for the students who have honors, divide the total amount of students with honors with the total amount of students.

\frac{Honors}{Total} = \frac{79}{100}

Divide 79 by 100

79 \div 100 = 0.79

Your answer is 0.79

If d is the midpoint of the segment AC
3241004551 [841]

Based on the statement below,  if d is the midpoint of the segment AC, the  length of the segment AB  is  4.5cm.

<h3>What is the line segment about?</h3>

in the question given,

AC = 3cm,

Therefore,  AD and DC will be = 1.5cm segments each.  

We are given C as the midpoint of segment DB.

So CB = 1.5cm.

The representation of the line segment is:

A-----------D------------C-------------B

     1.5           1.5            1.5

Since AD, DC and CB are each 1.5cm segments. Then the equation will be:

= 1.5 + 1.5 + 1.5

= 4.5

Therefore, The length of the segment AB is 4.5cm.

See full question below

If D is the midpoint of the segment AC and C is the midpoint of segment DB , what is the length of the segment AB , if AC = 3 cm.
