Answer:
11.1
C is the correct option.
Step-by-step explanation:
We have been given the equation \(-x+3.9\) and we have to evaluate this expression for \(x=-7.2\)
In order to find the same, we can substitute x = -7.2 in the expression
\(-(-7.2)+3.9\)
Now, we know the rule (-)(-)=+
\(7.2+3.9\)
On adding, the numbers, we get
\(=11.1\)
Hence, the value of the expression at x = -7.2 is 11.1
C is the correct option.
