Triangle ABC has vertices at (3,1) and (6,4).Rotate this triangle 180 degrees about the origin then reflect it over the Y-Axis.
Tems11 [23]

Answer:

3, -1

6,-4

IDK about the third vertices, you didn't give the original coordinates!

Step-by-step explanation:

180 degree rotation= (x,y) to (-x,-y)

3,1 goes to -3,-1

6,4 goes to -6, -4

IDK about the third vertice, you didn't mention it.

Reflection over y-axis= (x,y) to (-x,y)

-3, -1 goes to 3, -1

-6,-4 goes to 6,-4

hope this helps!

Which inequality represents all values of x for which the product below is defined?
Vedmedyk [2.9K]

Step 1 ) Separate the 4 and x.

\displaystyle\sqrt{4x} * \sqrt{x+2}

↓

\displaystyle\sqrt{4} \sqrt{x} \sqrt{x+2}

Step 2 ) Simplify the square root of 4.

\displaystyle\sqrt{4} \sqrt{x} \sqrt{x+2}

↓

\displaystyle\ 2 \sqrt{x} \sqrt{x+2}

Step 3 ) Simplify.

\displaystyle\ 2 \sqrt{x} \sqrt{x+2}

↓

\displaystyle\ 2 \sqrt{x(x+2)}

This is now in its simplest form, so the final answer is...

\displaystyle\ 2 \sqrt{x(x+2)}

or it could be...

\displaystyle\ 2 \sqrt{x} \sqrt{x+2}

Either one is correct. Only difference is one is in simplest form and one isn't.
