If \(p(x)=\frac{3}{5}x+4\), what is (p(10))?
Answer and explanation
Correct answer: 10
Substituting \(x=10\), \(p(10)=\frac{3}{5}\times10+4=6+4=10\). Hence, 10 is the correct option. A value such as 9 can result from incorrectly evaluating \(\frac{3}{5}\times10\). Exam tip: To find the value of a polynomial, substitute the given number for \(x\) and follow the order of multiplication and addition carefully.
