In the expression -7x-5x2+5, what is the coefficient of x?
A. 7
B. 5
C. -5
D. -7
The coefficient of x is -7 (the term -7x has x as a coefficient).
Therefore, the answer is D.
To find the coefficient of x in the expression -7x - 5x^2 + 5, we need to look at the terms that have x attached to them. In this case, we have -7x and -5x^2.
The coefficient of x is the number that is directly multiplied by x.
Therefore, the coefficient of x is -7, which corresponds to option D.
To find the coefficient of x in the expression -7x - 5x^2 + 5, you need to identify the term that contains the variable x.
The term -7x contains the variable x. The coefficient of x is the number directly in front of x. In this case, the coefficient of x is -7.
Therefore, the correct answer is D. -7.
