Segment ab falls on line 6x + 3y = 9. segment cd falls on line 4x + 2y = 8. what is true about segments ab and cd?

they are parallel because they have the same slope of -2.

Step-by-step explanation:

In order to solve this you first have to clear both equations for Y in order to leave the equation in slope form:

6x+3y=9

3y=9-6x

y=3-2x

4x+2y=8

2y=8-4x

y=4-2x

Remember that the slope is the constant that is multiplying the x, so in both functions the slope is -2 when two functions share the same slope, they are perpendicular.

Option C They are perpendicular because they have slopes that are opposite reciprocals of 2 and negative one half

Step-by-step explanation:

step 1

Find the slope of segment AB

we have

This is the equation of the line into point slope form

The slope m is equal to

step 2

Find the slope of segment CD

we have

This is the equation of the line into point slope form

The slope m is equal to

step 3

we know that

If two lines are perpendicular, then the product of their slopes is equal to -1

In this problem

mAB=2  and mCD=-1/2

so

(2)*(-1/2)=-1

so

The lines are perpendicular

therefore

They are perpendicular because they have slopes that are opposite reciprocals of 2 and negative one half

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
