Simplify: 5x – 12y + 8x + 2x2 + 4x2 1. 13x2 – 12y + 6x4
2. 13x – 12y + 6x2
3. -3x – 12y + 6x2
4. 7x2y

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.

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
