Answer:
x = -4, y = 8
Step-by-step explanation:
y - 12 + 2y = 12
=> 3y = 24
=> y = 8
x = 8 - 12
=> x = -4
Answer:
- domain: all terms are defined for <em>all real numbers</em>
- solution: x = 6
Step-by-step explanation:
Rewrite the equation as a single exponential. After taking the log, the solution becomes obvious.

Answer:
50 days
Step-by-step explanation:
Step one:'
given data
Non member must pay a 6$ per day
let number of days be x
cost = 6x
member of the club pay 1$ but must pay a yearly membership fee of 250
cost = 250+x
Step two
equate the two expression to find x
6x=250+x
6x-x= 250
5x=250
divide both sides by 5
x= 250/5
x=50 days
Answer:
different
