There are 1200 students in a school. They are allowed to cast vote either only for X or for y as their school perfect. 50 of them cast vote for both and 24 didn't cast the vote. The candidate Y won the election with the majority of56 more votes than. 1)How many students cast the vote?
2)How many valid votes are received by X candidate?
3) show the result in even diagram?

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.

1/4 because there is 4 grades.

y=1/4x-4

step-by-step explanation:

table 3 represents a direct variation function. : )
