Answer:
(7b+9)(7b-9)
Step-by-step explanation:
Let m represent the number of miles this guy runs in a day.
He runs every day, so the minimum number of miles has to be greater than 0.
According to the problem statement, the max number of miles is 3.5 miles or less.
Translate this into a (symbolic) inequality.
3,6,9,12,15 thats what i think. hope it helps
Answer:
C
Step-by-step explanation:
Use the formula for the discriminant.
In constructing an inequality, you need to know the following:
1. What don't we know? How many songs can be bought? So, let x be the numbers of songs.
2. What do we know? Each songs costs $2 plus a fee for using the artist's site of $5.
3. Is there more than 1 possible solution? Yes, because there is enough money left if she only bought 1 song.
The meaning of no more than $40 means it must not exceed $40, $40 or less, or only $40.
So, song + fee can't be more than $40 and song + fee could equal to $40.
Therefore, song + fee for using an artist's site less than or equal to $40.
Final Answer: 2x+5 <= 40
