' 36 = 9k ' is not an inequality. It's an <u>equality</u>, usually called an <em><u>equation</u></em>.
It's true whenever 'k' is 4, and false at any other time.
(You can determine that simply by dividing each side of the equation by 9.)
Answer:
The answer is 'C' "The slope of line BC is equal to the slope of line segment DE"
Step-by-step explanation:
This is correct. I checked my answer for this about 3 times. If this isn't correct then my next bet is answer 'D'

Using the together rate, it is found that they would prepare the solution in 1.71 minutes working together.
<h3>What is the together rate?</h3>
It is the sum of each separate rate.
In this problem, the rates are given by:
Hence the together rate is given by:



7x = 12
x = 12/7
x = 1.71.
They would prepare the solution in 1.71 minutes working together.
