Answer: 1+(-3)
Because you round the numbers, anything below 5 is rounded to 0 and anything 5 or above is rounded up. like 1.2 is 1, and 5.7 is 6.
The graph that models the pH of this solution is graph A.
<h3>What is a graph?</h3>
It should be noted that a graph is a diagram such as a series of one or more points, lines, line segments, curves, or areas which represents the variation of a variable in comparison with that of one or more other variables.
The pH is a measure of how acidic or basic water is. It should be noted that the range goes from 0 - 14, with 7 being neutral. The pHs of less than 7 indicate acidity, while a pH of greater than 7 indicates a base. The pH is really a measure of the relative amount of free hydrogen and hydroxyl ions that are in the water.
In this case, x represents the concentration of the hydrogen ions. The first graph illustrates this.

<u>Complete question:</u>
The ph of a particular solution is given by pH=-log(x-2) where x represents the concentration of the hydrogen ions in the solution in moles per liter. Which graph models the ph of this solution?
Answer:
You might be trying to figure out how many square feet are in a room so you can buy the right amount of paint or flooring, or maybe you're doing ... If you need the total square footage of the walls - for figuring paint or wallpaper for example ... •Area of a circle: The formula for this is: pi x radius2 (pi = 3.1416).
Step-by-step explanation:
The first angle given is not needed. it is extra info.
so to start off you need to see that it is a subtraction problem. it is angle BEF minus angle GEF
90 degrees minus 39 degrees then it is all math.
angle BEG = 51 degrees
the answer is x=-4 hope it helps
