Factor out the 4

4(x2 + 3x - 18)

what 2 numbers add to 3 and multiply to - 18?

-3 and 6

Select Is a Function or Is not a Function to correctly classify each relation. Title Is a Function Is not a Function
Sindrei [870]
<span>{(2, 2),(4, 4),(6, 6),(8, 8)} Is a function.
{(0, 3),(3, 5),(5, 6),(8, 4)} Is a function.
{(1, 2),(3, 3),(4, 8),(6, 3)} Is a function.
{(3, 4),(5, 2),(5, 6),(7, 3)} Is not a function. 

For a relation to be a function, every x value must have only one y value.

The points ​​ (0, −4)  and (3, 2)  lie on the graph of a linear function.   What is the rate of change of the function?   Enter
docker41 [41]
I don't entirely know what you mean by 'rate of change', but I'll assume that you mean slope.

0, -4 and 3, 2 are on the coordinate plane.

From 0, we go over three to reach 3.
From -4, we go up six to reach 2.

Since slope is in essence, rise/run, we have the following fraction:

6/3, which can be re-written as 2/1 or just 2.

Hope this helps!

Gnoma [55]

Answer:

Step-by-step explanation:

Note that 20 (an approximation for 205) less 4 (an approx. for 431) comes out to 16.

This tells us that the proper placement of the decimals is

20.50

-   4.31

----------

and this comes out to 16.19.
