No; a domain value has two range values.
x = -2 then y = 1 and 2
they would form a vertical line, which tells us that it's not a function
I can help! Do you have an example problem that I can show you step by step?
Find out what number goes into 8 and 10 then figure out how many times that number goes into 100
Set up the following equation for this segment:
x is segment AB's length, and 3x is segment BC's length. 20 is segment AC's length.
Combine like terms:
Divide both sides by 4 to get x by itself:
x will equal 5.
Plug this value into the values for both segments:
Segment AB:
Segment AB is 5 inches long.
Segment BC:
Segment BC is 15 inches long.
A is your answer! Because of how many sides it has.
