Question

Evalute the expression for the given value of the variable(s)

Answer 1

`-0.4`

1) Evaluate means to find a corresponding value given another one.

2) So, we can plug into that and find the value:

`\begin{gathered} 3d-4 \\ 3\left(1.2\right?-4 \\ 3.6-4 \\ -0.4 \end{gathered}`

Note that the corresponding value for d=1.2 in this model is:

`-0.4`
