9 feet above the ground, since it has to be 3 feet away from the wall you would have to subtract those 3 feet from the length of the ladder.

In a function, y varies inversely with x. The constant of variation is 4. Which table could represent the function?
Colt1911 [192]
I don't see a table but I can give you the means to answer it yourself.  The inverse function is represented by this: y= \frac{k}{x} where k is your constant.  You are given a k value of 4.  If you solve this for k then you will get xy=4.  In your tables, multiply your x value by your y value within your coordinate points and if you get a product of 4 each time you multiply x by y, then that table is your answer.

What is 9c+90<-27?????​
antoniya [11.8K]
<h3>Answer:  c < -13</h3>

========================================

Work Shown:

9c + 90 < -27

9c + 90 - 90 < -27 - 90 .... see note 1

9c < -117

9c/9 < -117/9 ... see note 2

c < -13

-----------

note 1: I'm subtracting 90 from both sides to undo the "plus 90" that is happening on the left side

note 2: I divided both sides by 9 to undo the multiplication. The expression 9c is the same as 9*c or "9 times c". The inequality sign will <u>not</u> flip as we are dividing both sides by a positive number.
