Answer:
Step-by-step explanation:
Let's rewrite the left side keeping in mind the next propierties:
Therefore:
Now, cancel logarithms by taking exp of both sides:
Multiply both sides by 
and using distributive propierty:
Substract 
from both sides and factoring:
Multiply both sides by -1:
Split into two equations:
Solving for 
Add 4 to both sides:
Solving for 
Collect in terms of x and add 
to both sides:
Divide both sides by e-2:
The solutions are:
If we evaluate x=4 in the original equation:
This is an absurd because log (x) is undefined for 
If we evaluate in the original equation:
Which is correct, therefore the solution is:
Answer:
ok so lets work this out
Step-by-step : 10/12 is closer to 12 than 7/12 soooo its not any of the ones that have these (:) and 10 is bigger than 7 so its
7/12 < 10/12
Answer:
b
Step-by-step explanation:
Answer:
2x-5
Step-by-step explanation:
f(g(x) means stick g(x) into f(x) in place of x
f(x) = 2x+1
f(g(x) ) = 2(g(x)) +1
and we know that g(x) = x-3
so replace g(x) with x-3
f(g(x) ) = 2(x-3) +1
Distribute
f(g(x)) = 2x-6+1
= 2x-5
The remaining values will be<u> 19, 20, 21, 22 and 23</u>
<h3 /><h3>System of equations</h3>
Given the following parameters
Ethan's score = x points
His younger sister's score = 8 points
If their total score is y points, hence the equation relating x and y is expressed as:
x + 8 = y
x = 8 - y
If x = 10
y = x + 8
y = 18
The ramining values will be<u> 19, 20, 21, 22 and 23</u>
