Recall that you can solve a percent problem by translating the words into an equation where the percent is written as a decimal. example: what percent of 20 is 5? translates as 5 = 20x x = 0.25, or 25% example: what is 40% of 20? translates as x = 0.4(20) x = 8 % of 630 is 189.

30% of 630 is 189.

16 is 20% of

⇒ 80.

30% of 630 is 189

16 is 20% of 80

Step-by-step explanation:

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
