There were 450 students enrolled in a middle school at the beginning of the school year. the number of students enrolled in the school at the end of the year was 10 percent greater than the number of students enrolled in the school at the beginning of the year. how many students were enrolled in the school at the end of the year?

495 students

Step-by-step explanation:

find 10% of 450:

450 x 0.1 = 45

45 students added through the year

now add 45 to the original 450 students

450 + 45 = 495

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

i believe that the answer is

b. y-1=-2(x-4)

hope this !
