j = # of jars
b = # of buckets
y = total # of rocks
2j + 3b = y (2 rocks per jar, 3 rocks per bucket)
Because Joy has 3 jars you can plug 3 in for "j", and because she has 4 buckets you can plug in 4 for "b"
2(3) + 3(4) = y
6 + 12 = y
18 = y
Answer:
Yes, the graph is a function.
Vertical line test proves so.
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It is the slope
b: It is the cut point with the y axis
We have the following equation:

Thus, the cut point with the y axis is -8. Therefore, we discard options C and B.
It is observed that the slope is positive so the correct graph is option B.
Answer:
Option B
Move all the logarithms on the left hand side, and all the constants on the other:

Use the rule of logarithms

To rewrite the equation as

Evaluate 2 to the power of each side:

Multiply both sides by 2x:
