Q. Point P is located at −7 . Points Q and R are each 7 units away from Point P. Where are Q and R located?Q=□R=□
Understand the problem: Understand the problem.We need to find the locations of Points Q and R, which are each 7 units away from Point P. Since no direction is specified, we assume that Q and R are on a number line with P at −7. There are two possibilities for Q and R: either both are to the left of P, both are to the right of P, or one is to the left and the other is to the right.
Determine Q location: Determine the location of Point Q.If Point Q is 7 units away from Point P and to the right, we add 7 to the position of Point P.Q=P+7Q=−7+7$Q = \(0\)
Determine R location: Determine the location of Point R.\(\newline\)If Point R is \(7\) units away from Point P and to the left, we subtract \(7\) from the position of Point P.\(\newline\)\(R = P - 7\)\(\newline\)\(R = -7 - 7\)\(\newline\)\(R = -14\)
