If (x=0), what is the value of (7x+2)?
Answer and explanation
Correct answer: \(2\)
Given \(x=0\), substitute it into \(7x+2\): \(7(0)+2=0+2=2\). Therefore, the correct value is \(2\). The number \(7\) is only the coefficient, not the value of the expression. Exam tip: To evaluate an expression, substitute the given value of the variable everywhere it occurs.
