What is the result of adding these two equations?

4x - 4y = -2

-9x - 4y = -3

(1/13, 15/26)

Step-by-step explanation:

If you really want to add them without doing anything to them, we get:

    4x - 4y = -2

+  -9x - 4y = -3

=   -5x - 8y = -6

But I suspect you want to solve for x and y.

In this case, if you want to eliminate and solve for x and y, we will subtract instead to make it easier:

    4x - 4y = -2

-   -9x - 4y = -3

=   13x + 0y = 1

    13x = 1

    x = 1/13

Plug x back in to get y:

    4x - 4y = -2

    4(1/13) - 4y = -2

    4/13 - 4y = -2

    4y = 30/13

    y = 15/26

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.
