Answers:
Figure a has been translated only (translated 9 units to the right)
Figure b has been reflected over the x axis
Figure c has been rotated and translated
=======================================
Explanation:
Pick on a point like (-7,4) and note how it moves 9 units to the right to get to (2,4). All points on the upper left figure follow this same translation rule. This rules in figure a.
Figure b is a result of reflecting over the x axis. The rule used is . The x coordinate stays the same while the y coordinate flips from positive to negative. So for example, (-7,4) flips to (-7,-4)
Figure c is a combination of rotating and translating the original figure. It looks like a 90 counterclockwise rotation has been applied followed by a translation. The actual translation and rotation rules used will depend on how you define the center of rotation.
129 FT of fencing is required for the problem

-12x - 32y = 4</h2>
Step-by-step explanation:
If we divide second equatoin by (-4) we get the first equation.
Two identical equations means infinite number of solutions.
Well, estimate means to get like a general idea, or "in the ball park".
The factors include; the trip which is $26, and the ammount of students in the class, which is 22.
In order to estimate, you need to round.
$26 rounded becomes $30.
22 rounded becomes 20.
So now that we have the rounded numbers, we solve the problem. In order to find the total cost for all the students, we multiply the amount of students, by the ammount of money it costs per student.
The estimated version of this is: 20x30=600
This means that the estimated answer is $600 total.
Now do the same thing with the actual numbers.
22x26=572.
This means that the actual answer is $572.
The roumded total
Answer is $600.
You can say it is better use the actual numbers, and not estimate, because it is the actual answer.
I hope this helps you, im sorry for the long answer :)
