Answer:
(a) Reflection across the y-axis, followed by translation 10 units down
Step-by-step explanation:
Figure 2 is not a reflection across the origin of Figure 1, so neither of the double reflections will map one to the other.
Reflection across the y-axis will put the bottom point at (5, 3). The bottom point on Figure 2 is at (5, -7), so has been translated down by 3-(-7) = 10 units.
Figure 1 is mapped to Figure 2 by reflection over the y-axis and translation down 10 units.
Answer: x = -3, -1/3, 1/2, 3

Answer:
The answer is D. water fountain.
Step-by-step explanation:
If you look at the graph for the point (-2.5, 3.0), you need to find -2.5 on the x-axis and 3 on the y-axis. The "Water Fountain" point is past negative two but not quite at 3 yet; it's in between. Then you go up three times. Even though the graph is going by 2's, the point is located exactly in between 2 and 4, which is 3. Hope this helps!
<u>EXPLANATION </u>
First you will need <u>TWO</u> numbers. One being the percentage and the other being the number your trying to find the percent out of.
<u>EXAMPLE</u>
Imagine you have 130 crayons. Out of the 130 crayons you found that 15% of them were broken.
First you want too take the 15% and put it over 100, because a percentage always goes over 100. Now that you have the 15/100 you now wanna take the 130 crayons and put the variable <u>X</u> over it. Now that you have the fractions 15/100 and X/130 you want to cross multiply them to get <u>100x </u>and <u>1950</u>. For the final step your going to want to take 1950 and divide it by 100 to get your answer, <u>19.5</u>.
I hope this helped you find out the method for solving a percentage problem while using proportions.
