What is a polynomial Can anyone answer with the definition of Quadrilateral
pashok25 [27]

Polynomial is an expression of more than two algebraic terms.

<h3>Definition of quadrilateral:</h3>
  • A quadrilateral is a four-sided polygon with four edges (sides) and four corners in geometry (vertices).
  • The name comes from the Latin words quadri, which means "four," and latus, which means "side."
  • In comparison to other polygons, it is also known as a tetragon, derived from the Greek "tetra" meaning "four" and "gon" meaning "corner" or "angle"
  • In the same way as other polygons (e.g. pentagon). While "gon" means "angle," it's also known as a quadrangle or 4-angle.

The graph below represents the following system of inequalities. y&gt;x-2 y&gt;2x+2 which points (x,y) satisfies the given syste
kramer

Answer: (-4,-6) is the point that ALMOST satisfies both inequalities. IF they were equalities, this would be the solution.

The question is a bit confusing as it asks for "which points (x,y) satisfies both" It's ungrammatical, and many points (infinite within the shaded region) are solutions that SATISFY the system of inequalities!

Step-by-step explanation: Substitute the x and y-values and see if the inequalities are true.

y>x-2 -6> -4-2 -6= -6

That point (-4,-6) is on the dashed line, so not exactly a true solution; this is a question about inequalities. So y values have to be greater than-6 or x-values less than -4 for a true inequality.

y>2x+2

-6>(2)(-4) +2

-6> -8 +2

-6> -6 Again, equal, so for this y-values have to be greater than-6 and/or x-values less than -4 in order to have a true inequality.

If you have the graph to look at, you can select any points in the shaded region that satisfies both of the inequalities.
