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:
I am trying hard to help give me a second
Emory has the least siblings (1), is 29 years old, and gets paid $7.28 per hour. (Note the units included in the age (years) and wage ($ per hour) columns.)
Let y = total cost of the taxi service.
let x = amount of miles
We need to create a system of equations to solve this problem.
Taxi company 1: y = $0.25x + $5
Taxi company 2: y = $0.50x + $1
Set the equations equal to each other
$0.25x + $5 = $0.50x +$1.
Subtract $0.25x from both sides and subtract $1 from both sides.
$4 = $0.25x
Divide both sides by $0.25.
16 miles = x
The companies will charge the same amount of money at 16 miles
