The horizontal axis is an independent variable, the vertical axis is dependent on the independent variable. So to describe how variables change in relation to each other, ask "what is happening to the dependent variable as the independent variable changes?" in this case time is increasing from left to right, what is happening to the water?

Let length=x, witdth=x-9
Perimeter=130
2 length+2 width=130
2x+2(x-9)=130
2x+2x-18=130
4x=130+18
4x=148
X=37 cm

Length=37cm; width=37-9=28cm

Hope this can help.

Can somebody help me with this question?

V125BC [204]

Answer:

$\frac{2}{5}\vec{a}+\vec{b}$

Step-by-step explanation:

$\vec{DE}=\vec{DB}+\vec{BE}$

$=\frac{3}{5}\vec{OB}+\frac{1}{5}\vec{BC}$ $\left\{OD:DB=2:3,BE:EC=1:4\right\}$

$=\frac{3}{5}\left(\vec{OA}+\vec{AB}\right)+\frac{1}{5}\left(\vec{BA}+\vec{AO}+\vec{DC}\right)$

$=\frac{3}{5}\left(\vec{a}+\vec{b}\right)+\frac{1}{5}\left(-\vec{b}-\vec{a}+\vec{3b}\right)$

$=\frac{2}{5}\vec{a}+\frac{2}{5}\vec{b}+\frac{3}{5}\vec{b}$

$=\frac{2}{5}\vec{a}+\vec{b}$

I hope this helps you

The set notation of [-5,16) is?

valentina_108 [34]

Answer: $\left\{x | x \in \mathbb{R}, \ -5 \le x < 16\right\}$

=======================================================

Explanation:

We have some number x such that x is a real number, so we write that as $x \in \mathbb{R}$ which is saying "x is in the real number set".

The portion $-5 \le x < 16$ is how x is restricted. This means x can be -5 or larger, but also must be smaller than 16.

This is from the interval notation [-5, 16). The square bracket means we include -5 as part of the interval, but we exclude 16 because of the curved parenthesis.

The curly braces surrounding everything indicates that we have a set of values.

-----------------

Side note:

If x is an integer, then we can get this roster set {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15} showing all of the integers between -5 and 16, including -5 but excluding 16.

Though chances are your teacher will want you to stick to real numbers rather than just integers.
