Hi there!  When talking about interval notation, we use regular parentheses e.g. (). Interval notation is a way to describe continuous sets of real numbers by the numbers that bound them. When written, they look somewhat like ordered pairs. Although, they are not meant to denote a specific point. They are meant to be a shorthand way to write an inequality or system of inequalities.

With interval notation, we use use square brackets e.g. [ ].

With inequalities, we use "less than or equal to" ≤ or "greater than or equal to": ≥ to include the endpoint of the interval. Inclusive inequalities with the “or equal to” component are indicated with a closed dot on the number line and with a square bracket using interval notation. Strict inequalities without the “or equal to” component are indicated with an open dot on the number line and a parenthesis using interval notation

Hope this helps! Have a good day!!

On a special right triangle if the sides are 6 and 6 then what is the hypothinus
Black_prince [1.1K]
We are talking about a right triangle so the phytagoras equation can be used:
a^{2} + b^{2} = c^{2}
6^{2} + 6^{2} = 36 + 36 = 72 =  c^{2}
\sqrt{ c^{2} } = \sqrt{72} =8.48528...
So the hypothinus is equal to approximately 8.49

Shown here is the graph of which inequality? Please can’t figure it out I need SOME HELP
Annette [7]

Hey there!

Three points to keep in mind!

  • The given options are in standard form: ax+by=c
  • The line is a solid line, hence, the possible outcomes would be ≤ or ≥
  • The shaded part is above the line, hence, the symbol would be ≥

First, let's find the slope:

Slope : (y2-y1)/(x2-x1)

Slope : (0-3)/(2-0)

Slope : -3/2

Looking at line, we know that the y-intercept is 3 b=3

Slope intercept form:

<em>y≥(-3/2)x+3 </em>

Let's now convert this into a standard form:

<em>(3/2)x+y≥3 </em>

<em>Multiplying all the sides with 2: </em>

<em>Remember that the coefficient of 'x' shall not be negative or a fraction!</em>

<em>3x+2y≥6 </em><em>is the final answer!</em>
