The answer to the graph is most likely to be B
Take any 2 points from the given line and use the rule to find slope
(3,0) (0,-1)
Slope= y2-y1/x2-x1
Slope= -1-0/0-3= -1/-3 = 1/3
Final answer :
Slope = 1/3
So it’s the first option :)
Answer:
Step-by-step explanation:
U just set that as an equation. So it would be like this... 3x+3= 63.
3x + 3 = 63
-3 - 3
3x = 60
/3 /3
X = 20
Answer:
Step-by-step explanation:
The logarithm function is monotonic with a positive slope everywhere. So, the logs of numbers are in the same order as the numbers themselves. pH is the negative of the logarithm, so the pH values are in the reverse order of the numbers themselves.
Maura's pool has a lower pH, so will have a higher concentration of hydrogen ions.
The log of a ratio is the difference of the logs. Here, the difference of the logs is 7.8 -7.2 = 0.6, so the ratio of H+ concentrations in the two pools is ...
10^0.6 ≈ 4.0
Maura's pool has 4× the H+ concentration of Bill's pool.
