The sum of the lengths of any two sides of a triangle is greater than the length of the third side. In AABC, BC = 4 and AC = 8 - AB. What can you conclude about AB?

d. vertex

step-by-step explanation:

faster, im not sure why but i know it is faster

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
