You distribute the 30x to the equation in parenthesis

So basically you are doing (30x*x)+(30x*-3)
So you get 30x^2-90x

Hope this helps!

30x(x-3)
lets substitute x for 1
30 * 1(1 - 3)
1 - 3 = 2
30 * 1 = 30
30 * 2 = 60
I hope I did it correctly.

Which graft represent -3x+5y=-15
azamat

The graph of the function -3x+5y=-15 is a linear function we can draw it by finding the values of y for every value of x.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

-3x + 5y = -15

The above function shows a linear function we can write it as:

5y = 3x - 15

y = (3x - 15)/5

If x = 0, y = -3

x = 1, y = -2.4

x = 2, y = -1.8

x = -1, y = -3.6

x = -2, y = -4.2

Thus, the graph of the function -3x+5y=-15 is a linear function we can draw it by finding the values of y for every value of x.
