Step-by-step explanation:
the domain of 3^x is (-∞,∞) and the range is (0,∞)
the domain of 3^x-5 is (-∞,∞) and the range is (-5,∞)
the domain doesn't change, the range (-5,∞)
Answer:
Brian: 22
Charlie: 88
Latoya: 14
Step-by-step explanation:
Set up an equation where b represents the number of messages Brian sent:
4b will represent Charlie because he sent 4 times more texts than Brian did
(b - 8) represents Latoya because they sent 8 less texts than Brian:
b + 4b + (b - 8) = 124
Add like terms:
6b - 8 = 124
6b = 132
b = 22
Now, we can plug in 22 as b to find Charlie and Latoya's number of texts:
4b = 4(22) = 88
b - 8 = 22 - 8 = 14
