In functions, the coefficient is the number that multiplies the variables, for example, for 5y, the coefficient is the number "5"
The "leading coefficient" refers to the number that multiplies the greater term of the expression (i.e. the term with the largest exponent), and if the terms are ordered from greatest to least, it corresponds to the coefficient of the first term.
So for the expression

The first and the term with the largest exponent is:

Where "6" is the coefficient of the term and thus the "leading coefficient" of the expression.
I believe it is c because it is definitly not biased because they were selected at random. And d. Is incorrect
Hope this helps let me know if you need help
when the song is at 1, the cost is 0.99, when the songs are at 2, the cost is $1.98
Divide the cost by the number of song: 1.98 / 2 = 0.99 per song.
The unit rate is $0.99 per song.
2 lawns per hour is the answer
