What do you think?
I think it's 4, but is that the only coefficient?
Yes.
Ohhh okay thanks.
You're welcome.
To identify the coefficients in the expression 4x + 9 - y, we need to understand that coefficients are the numbers multiplied by variables. In this expression, the coefficients are 4 and -1.
Here's how to identify the coefficients step by step:
1. Look for the variables in the expression. In this case, the variables are x and y.
2. Check if there is a number directly preceding or following the variable. If yes, that number is the coefficient.
4x: Here, 4 is the coefficient of the variable x because it is directly multiplied with x.
-y: In this case, -1 is the coefficient of the variable y because -1 is directly multiplying y.
3. Ignore any numbers that are not directly multiplying or dividing the variables.
+ 9: The number 9 in this expression is not directly multiplying or dividing any variable. Therefore, it is not a coefficient.
In conclusion, the coefficients in the expression 4x + 9 - y are 4 and -1.
