Question

Evaluate -9x when x = 2

Answer 1

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

Answer 2

Answer:

-18

Step-by-step explanation:

x=2 so,

-9(2) = -18
