Answer:
s = 4 or = -4
Step-by-step explanation:
They charge $30 per month as a base so that is y
They also charge $0.25 per text message, this is x
so $0.25x+$30y=$59.50
first subtract 30 from both sides to get x alone
$0.25x=$29.50
To find amount of text messages sent, we have to divide
$29.50/$.25
29.50/.25=118
This person sent 118 text messages
The answer is D because it asked 7 or more
Answer:
It is true, except when x = 2/5, since it is an asymptote.
Step-by-step explanation:
3x=5xy-2y
3x=y(5x-2)
3x/5x-2=y
5x-2=0 -------> 5x=2 --------> x=2/5
