Answers:

Letter F: none
Number 3: line and plane simmetry
Letter E: line and plane simmetry

Explanation:

1) point symmetry means that a rotation of 180° returns the same original figure.

None of the objects given result the same when you rotate them 180°, so none has point symmetry.

2) line simmetry is when the reflection accross a line returns the same original figure.

Both number 3 and letter E have symmetry accros a horizontal line that crosses them by the middle, which F does not.

3) Plane simmetry: exactly as with the line,number 3 and letter E have simmetry accross a plane that crosses them by the middle.

Which matrix is equal to P + Q?
Afina-wow [57]
Answer: 
\begin{bmatrix}-1.1 & 9.5\\-5.7 & 0.8\\6.1 & 0.7\end{bmatrix}

------------------------------------

Add up the corresponding elements

Row1,Column1: 6.1+(-7.2) = -1.1
Row1,Column2: 1.9+7.6 = 9.5
Row2,Column1: -7.5+1.8 = -5.7
Row2,Column2: 2.2+(-1.4) = 0.8
Row3,Column1: 3.8+2.3 = 6.1
Row3,Column2: -1.4+2.1 = 0.7

So that's why the answer is 
\begin{bmatrix}-1.1 & 9.5\\-5.7 & 0.8\\6.1 & 0.7\end{bmatrix}

Find 490 and either go up 2 down 1 or down 2 up 1 either way you will get a straight line.

3. f(x)=2x+490

Don-t know how to explain this :(
