Answer:
The Domain is x < 3
Step-by-step explanation:
We know that ln(x) is defined for all real numbers that are greater than zero, or x > 0.
Knowing that we must make the inside of ln(x) greater than 0 so:
Multiply both sides by 2:
Add x to both sides:
or 
Answer:
16
Step-by-step explanation:
Answer:
x = -5
, y = 1
Step-by-step explanation:
Solve the following system:
{3 x + y = -14 | (equation 1)
-2 x - y = 9 | (equation 2)
Add 2/3 × (equation 1) to equation 2:
{3 x + y = -14 | (equation 1)
0 x - y/3 = (-1)/3 | (equation 2)
Multiply equation 2 by -3:
{3 x + y = -14 | (equation 1)
0 x+y = 1 | (equation 2)
Subtract equation 2 from equation 1:
{3 x+0 y = -15 | (equation 1)
0 x+y = 1 | (equation 2)
Divide equation 1 by 3:
{x+0 y = -5 | (equation 1)
0 x+y = 1 | (equation 2)
Collect results:
Answer: {x = -5
, y = 1
