I hope you see the pattern here . When multiplying the exponent (the small number near the 10) determines the number of zeros to the RIGHT . When dividing the number determines how many zeros to the LEFT usually resulting in a decimal. This is called scientific notation.
Hope this helps!:)
OK so where is the weekly math homework!?
Answer: it is d becaues that is the mode
Answer: Choice A
---------------------------------
Explanation:
The rule I'm going to use is if |x| <= k, then -k <= x <= k
where k is some positive number
The notation <= means "less than or equal to"
|2x-6| <= 10
-10 <= 2x-6 <= 10 ... use the rule mentioned above
-10+6 <= 2x-6+6 <= 10+6 ... add 6 to all sides
-4 <= 2x <= 16
-4/2 <= 2x/2 <= 16/2 ... divide all sides by 2
-2 <= x <= 8
So we'll have a number line with closed circles at -2 and 8. The shaded region is between the closed circles.
This is a shorthand way of saying what choice A is saying. For some reason, your teacher decided to make the wording more clunky.
Saying "shading to the right of -2 and shading to the left of 8" is the same as "shading between -2 and 8"
So that's why choice A is the answer
Note: the closed circle indicates we include the endpoint as part of the solution set, or shaded region.
