3^3 * 7^r has (3 + 1)*(r + 1) = 16 factors.
So r must be 3.
Answer:
Step-by-step explanation:
I'm going to presume you want this linear equation in slope-intercept form, so start with:
Subtract 
from both sides of the equation:
Subtract 
from both sides of the equation:
Divide both sides of the equation by the coefficient of 
, which is 
:
Simplify:
Answer:
