40 points students are given 3 minutes to complete each multiple-choice question on a test and 8 minutes for each free-response question. there are 15 questions on the test and the students have been given 55 minutes to complete it. test time number of time per item questions (minutes) total time (minutes) 3m 15-m multiple choice free response total which value could replace x in the table? 55 o 7-m o 23-m o 8(15 – m) o 8(15) - m

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

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.
