What is the coeficient in the following expression?
5a-7

The coefficient is 5

The answer is B. 5

Step-by-step explanation:

A coefficient is a number that is multiplied with a variable. In this example, 5 is multiplied with a2 so 5 is a coefficient.

In addition, the −7 in this expression is called a constant, which is a number NOT multiplied by a variable. There is usually one constant in an expression but there can be multiple coefficients depending on the variables and their degrees (or powers, e.g x,x2,x3,...)

ex: 5x2+2x+4

Here the constant is 4 and there are two coefficients: 5 and 2 but only 5 is what is known as the leading coefficient which is the coefficient being multiplied by the variable with the highest degree (In this case: x2 has a higher degree than x)

the answer is c. 23/3
