Answer:

A parallelogram has two parallel pairs of opposite sides. A rectangle has two pairs of opposite sides parallel, and four right angles. It is also a parallelogram, since it has two pairs of parallel sides.

How can you tell whether an ordered pair is a solution of a linear inequality?

sweet-ann [11.9K]

Hello from MrBillDoesMath!

Answer:

Suppose the ordered pair is (x.y). Substitute these values in the linear equality to see if it is true,

Example. Consider the point (7, -4). Is it a solution of the linear inequality

3x < 4y - 9? Let's check to find out.

Check:

Is 3 (7) < 4 (-4) - 9 true ?

Is 21 < -16 -9 = -25 ??

NO!

So (7,-4) is NOT a solution of the linear inequality.

Thank you,

MrB

Help me guys fast as

Viktor [21]

cos(180-x)=-cosX

$\\ \rm\Rrightarrow tan^2135-cosec^260=-xcos45.sin45.cot60$

$\\ \rm\Rrightarrow (-1)^2-(\dfrac{2}{\sqrt{3}})^2=-\dfrac{x}{\sqrt{2}}\times \dfrac{1}{\sqrt{2}}\times \dfrac{1}{\sqrt{3}}$

$\\ \rm\Rrightarrow 1-\dfrac{4}{3}=\dfrac{-x}{2\sqrt{3}}$

$\\ \rm\Rrightarrow \dfrac{3-4}{3}=\dfrac{-x}{2\sqrt{3}}$

$\\ \rm\Rrightarrow \dfrac{-1}{3}=\dfrac{-x}{2\sqrt{3}}$

$\\ \rm\Rrightarrow \dfrac{1}{\sqrt{3}}=\dfrac{x}{2}$

$\\ \rm\Rrightarrow x=\dfrac{2}{\sqrt{3}}$
