Concept explainers
To describe: Whether the equation (a) or (b) is a translation of the given statement.
Answer to Problem 4WE
Hence, the translation (a)
Explanation of Solution
Given information:
The given statement is four less than twice a number is nine: (a)
Method used:
N less than y means addition of −N, i.e.,
Calculations:
Let the number is x , then the statement reads “4 less than twice of x is 9”.
Mathematical form of the statement is two times of x minus 4 is 9.
Thus, translated statement is
Hence, the translation (a)
Conclusion:
Hence, the translation (a)
