Step-by-step explanation:

The expression is 2 - m/4 + 10, when m = 12, the value is 9. Then the correct option is C.
<h3>What is the linear system?</h3>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Two less than the quotient of a number and four, increased by ten.
That can be written as in the form of m will be

If the value of m is 12, then we have

Thus, the expression is 2 - m/4 + 10, when m = 12, the value is 9. Then the correct option is C.
