6x(2)y +8xy(2) - 10x(2)y - 15xy + 9xy(2) simplify

-4x²y + 17xy² - 15xy

Step-by-step explanation:

Step 1: Write out expression

6x²y + 8xy² - 10x²y - 15xy + 9xy²

Step 2: Combine like terms (x²y)

-4x²y + 8xy² - 15xy + 9xy²

Step 3: Combine like terms (xy²)

-4x²y + 17xy² - 15xy

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.
