Okay, first of all, you are probably stuck and don't understand what an exterior angle is. I don't know how to explain it but the exterior angle in this case is ∠DAB.

<h2>∠DAB = ∠ABC + ∠BCA</h2><h2>            = 90° + 62°</h2><h2>= 152°</h2><h2 /><h2>They said that the exterior angle was instead 128 degrees. This means that now the sum of the angles of B and C are 152 degrees, or, 152 - 128 = 34 degrees greater.</h2>

Use this equation : y=6-4x
xenn [34]

Answer:

For table :

X------Y

0------6

1------2

Figure show equation of line: y=6-4x

Step-by-step explanation:

Given equation is y=6-4x

To plot the equation of line, we need at least two points.

Take x=0

The respective value of y on line is

y=6-4x

y=6-4(0)

y=6

The required point is A(0,6)

Take x=1

The respective value of y on line is

y=6-4x

y=6-4(1)

y=2

The required point is B(1,2)

For table :

X------Y

0------6

1------2

Figure show equation of line: y=6-4x

True or false? If you took a true "if-then" statement and reversed the clauses, the new statement would also be true
lbvjy [14]

That's false.

Here's a counter-example:

If an animal is a dog, then it has four legs.  This is true.
but
If an animal has four legs, then it is a dog.  This is not necessarily true.


Another one:

If a shape is a square, then it has four sides.  Always true.
but
If a shape has four sides, then it is a square.  Usually not true.

√8x^2 divided by √2x
Ghella [55]
Question: Simplify \frac{\sqrt{8x^2}}{\sqrt{2x}}.

First off, you <em>never</em> want square roots on the bottom of a fraction, so let's multiply both sides by \sqrt{2x} to get rid of it. All we have to do from there is simplify!

\frac{\sqrt{8x^2}}{\sqrt{2x}}*\frac{\sqrt{2x}}{\sqrt{2x}}=\frac{\sqrt{8x^2}*\sqrt{2x}}{2x}}=\frac{\sqrt{16x^3}}{2x}=\frac{4x\sqrt{x}}{2x}=\boxed{2\sqrt{x}}
