Melanie is making a graph that contains the ordered pairs (-1, 1), (0, 1), (2, 1), and (4, 1). Will her graph represent a function? Why or why not?

Considering the ordered pairs that Melanie's graph contains, each x-value has exactly one y-value assigned to it, therefore Melanie's graph represents a function.

Thus, considering the ordered pairs that Melanie's graph contains, each x-value has exactly one y-value assigned to it, therefore Melanie's graph represents a function.

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
