B (5t + 15 ≤ 140) is correct

Step-by-step explanation:

Because since each table (t) seats 5 people, you'd represent that as 5t (5 seats per table).

Since there is one extra table that seats 15 people, you'd represent that as 15.

Lastly, those two last steps added together should have to be less than or equal to (≤) 140 (the amount of people allowed in the building).

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.
