Answer:

Increasing

Step-by-step explanation:

The x-axis is the "time", and

The y-axis is the "water level".

As we go right in the x axis, the y axis increases. This is an example of increasing function.
As we go right in the x axis, the y axis decreases. This is an example of decreasing function.

In the line shown, as we go right in the x-axis (time axis), we see that the value of y axis (water level) increases (rises). According to the definition, we can clearly say that this function is increasing.

How do you solve and graph -82 is less than or equal to 9x OR -1 is less than or equal to -28

vovikov84 [41]

Since $-1\nleq-28$ , you can eliminate this part.

So you're left with
$-82\leq9x$
⇒ $9x\geq-82$
⇒ $x\geq-\frac{82}{9}$

which is about -9.11111...

What is the factored form of x2 – x – 2? (x – 2)(x 1) (x 2)(x 1) (x – 2)(x – 1) (x 2)(x – 1)

Alexxx [7]

A quadratic equation is an equation whose leading coefficient is of the second degree. The factored form of the quadratic equation x²-x-2 is (x+1)(x-2).

<h3>What is a quadratic equation?</h3>

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.

It is written in the form of ax²+bx+c.

The factored form of the quadratic equation can be done in the following manner,

$x^2-x-2\\\\= x^2-2x+x-2\\\\=x(x-2)+(x-2)\\\\=(x+1)(x-2)$
