1 answer:
Answer:
12.
-1.9 , -1.8, -1.7
13.
Points in Quadrant IV have a positive x, and a negative y.
14.
The point (2,9) is reflected over the y-axis, which means the number in x has it's sign flipped.
(-2 , 9) is your answer
15.
In between -7 & -4 is <em>-6, -5</em>
b. -6 is your answer.
16.
Remember that Quadrant II has a negative x, and a positive y. This means that b. (-2, 5) is your answer.
17.
You are reflecting over the y-axis, so you are changing the sign of the x value.
(-3, 5) reflected over the y-axis is a. (3 , 5)

Answer: Last option.
Step-by-step explanation:
In order to estimate the percent "n" of a number"x", you need easy numbers to work with, therefore you can round "n" and "x" up or down; but it is important to remember that this estimation does not give you an exact value.
You can observe that Sergei's first step was to round 149% and 67 up, getting this result:
To verify if this estimate is less or greater than the actual answer, we can find the actual answer. This is:
Therefore, we can conclude that<em> the estimate is greater than the actual answer because the percent and the number were both rounded up</em>.
