Hey there! :D
21= 2x-6+x
21=3x-6
27=3x
x=9
The smaller number is 9.
The larger number is:
9*2= 18 18-6= 12
The larger number is 12.
I hope this helps!

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cutoff point with the y axis
We need two points through which the line passes to find the slope:

We found the slope:

So, the equation is of the form:

We substitute a point to find "b":

Finally, the equation is:

Answer:
Option D
Answer:
- 
Step-by-step explanation:
Evaluate cosπ then inverse tan, that is
cosπ = - 1
(- 1) = -
