Question

on a math test a student, has to identify all the coefficients and constants of the expression 5y+b+4. Jake says that 5 is a coefficients and 4 constant. Identify all the coefficients and constants of the expression. what error might jake have made?

Answer 1

First, define what is a constant and a coefficient.

Constant = Is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number.

Coefficient = Is a number used to multiply a variable, for example 6x, 8x, or 5y, also sometimes a letter if it is accompanied by a variable example bx.

`5y+b+4`

In this expression, b and 4 are constants. And 5 is a coefficient because it is accompanied by y.

Jake missed b as a constant.
