Mis the midpoint of AB. If the length of the line segment AM is 20, and the length of the line segment MB is 3x + 8, what is the value of x?

x = 4

Step-by-step explanation:

We know that M is the mid-point of AB. So,

AM = BM ( A mid point divides a line segment into 2 equal parts. )

Also it's given that length of AM is 20 & length of BM is 3x + 8.

But as AM = BM ,

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
