Answer:
Step-by-step explanation:
D. If you were to graph this, the vertex would be at (9/8,101/4), or (1.13,25.25).
It’s A because when you add the anti force to the molecular cause of the yah
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.
