Answer:
-18
Step-by-step explanation:
Between any number (in this case -9) and letter (in this case x) in an algebraic equation, there is an invisible multiplication.
-9 × x
the question states that x = 2, so we can substitute the 2 into the equation
-9 x 2
a positive number multiplied by a negative number always gives a negative number, and 9 x 2 = 18
∴ the answer to this equation = -18
The value of the expression is -18.
The given expression is -9x.
We need to find the value of the expression when x=2.
To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.
Now, substitute x=2 in -9x
We get, -9(2)=-18
Therefore, the value of the expression is -18.
