A). To go from ABCD to A'B'C'D' takes two transformations.
Step-1 : Reflect the original figure around the x-axis.
Step-2 : Slide the new figure 7 units to the right.
See the attached drawing. It shows the whole process
including the intermediate status and coordinates of
the four points after Step-1. You'll love it.
B). I looked up a definition of 'congruent'. It said that two figures
are congruent if they have have the same shape and size after
being moved, rotated,
or reflected. (I was worried about the
'reflected' part.)
Both elevations or numbers are already expressed as a
rational number. This is because a rational number is defined as a number that
can be expressed as a quotient or fraction of two numbers:
p / q
Since in this case, q may be equal to 1, then both are
rational numbers.
Answer:
g = 33%
Step-by-step explanation:
The values in the ends of the rows are found by adding together.
For the first row, we would add the value in cell AC to the value in AD to get the value in the corresponding column called "Total". This means we add 20% +g to get 53%;
Subtract 20% from each side
g = 53% - 20%
