Question

Which statement is true about the parts of this expression?

7.5y - z/9 + 50 + 2y
The constant is 7.5.
The coefficients are 7.5 and Negative 9.
The variables are x and y.
The like terms are 7.5 y and 2 y.

Answer 1

First, False b/c 7.5 is not the constant because it multiplies by y ==> 7.5 is a coefficient
Second, False because -z/9, you can understand it as . So, 7.5 and -1/9 are the coefficient, not 7.5 and -9.
Third, False, because z and y suppose to be the variable, not x and y variable.
Last, True because they both have the term y multiplies by a coefficient.

Answer 2

we have z as a variable too, so 3 is wrong
1 is wrong b/c we have -1/9 as a constant
2 wrong bc2 is also a coefficient

Answer 3

Everybody thank you.

Answer 4

np : ) have a good day!

Answer 5

same too
