Tank A is filling quicker
Step-by-step explanation:
You can tell this by looking at the slope of each line. Since the slope of line A is larger and going up faster, that tells you that tank A is filling faster than tank B
Answer:
what range
Step-by-step explanation:
range of
ano pong range
The technology I used in helping me solve the problem is using Microsoft Excel. I made one column for the x values which were gathered from the choices, one column for f(x) whose equation is 8^(x-9), and another column for g(x) whose equation is log(3x) + 2.
Inputing these equation to the last two columns yield the values shown in the picture.The 'NUM' means that the equation at that value of x is undefined. From the values, the correct solution would be
(0,0), (9.2,1.5) and (9.6,3.5) to the f(x) equation
(9.6,3.5) to the g(x) equation
