When we are drawing rotations, we turn the paper to get a look at were and how the figure is going to rotate. This will predict where and how the rotation will turn out because the figure moves around and makes it seem like the figure change quadriant. A rotated figure doesn't change in shape, size, but it changes location. A rotated figure differs from a reflection is when the figure for example is looking itself in the mirrow. If you would rotate a figure 90 degrees clockwise and then rotate it again 90 degrees counterclockwise you will end up were you started.
The figure will change quadriant. when you go clockwise you are goinh to the right but when going counterclockwise you are going the apposite.

"Transformations - Reflections"
A reflection is like a mirror image because, a reflection is to flip over a line of symmetry, you can reflect or flip a figure over any line. The figure under a reflection is a mirror image of the original figure, is like the figure is looking at itself in the mirror. The line that figures is flipped over, a line along which a figure can be folded so that the two figures match. Yes, because they have already giving you the points of the original figure. When we look at two figures we know which on is transformation because it has the (") on top of each letter, so it makes it prime.

Transformations - Dilations
The figure can grow larger, zooming out or the figure can grow smaller, zooming in. Zooming relates to dilations because a dilated figure will either get larger or smaller. If the scale is greater than (1) the figure will get larger,so for 0.5 the figure will get smaller, because is lower than (1). Dilations are differ from translations because a dilation is when you change a figure's size without changing in shape, but in the other hand translation is sliding a figure to a differ location. Multiplying by 1/3 is the same as dividing by 3 because,just as dividing by 3 is the same as multiplying by 1/3 and, dividing by 1/3 is the same as multiplying by 3, to divide by a fraction is the same as multiplying by its reciprocal.

Transformations - Translation
I will know which one is is the transformation, because the point will be represented with
an apostrophe. The new points are called prime. One word I would use to describe a translation
is sliding. translation occurs when a figure slides across a coordinate plane. A translated figure will never change its shape because "translation" the shape only moves its direction it never changes shape or orientation of a figure.

"Laws of Exponents part 1"
Yes, we can expand any variable with an exponent, because for example 2^4 is 2x2x2x2 which is 16.The exponent of the y is y^1. X times x is x^2, it is not x because with x times x you have two x^5 .Yes, 6^3 is the same as 6x6x6 which is 216.When you have an exponent is the same as that number times itself.
"Laws of Exponents part 2"
To square a number is to times a number by itself by two(^2).To cube a number is to times a number by itself by three(^3).They relate because your multiplying the number by itself by power.Example, 3^4= 3x3x3x3= 81 .the area could be 3 and you have 4 sides.

"Integral Exponents"
We can't simplify expressions that do not contain like terms, because you can't make it
smaller.X^2 and xy^2 are not like terms because they are not the same, one has a y in it.
No xy is not the same as xyz, because xy does not have z, and you can't combine them. The power of m^7 is m to the seven power.The base is the m.A negative base is the opposite of a positive,for example the negative of 6 is -6, the negative of x is -x.
