Question

Sean and Rachel we’re both born on April 17.

Answer 1

Explanation:

let Sean be 4 years old and Rachel be 2 years old on April 17

part (A)

R=S-2 --(A)

is an equation that can be used to determine Rachel's age

likewise,

S=R+2--(B)

can be used to determine Sean's age

part (B)

use equation(A) for table (1) and equation(B) for table 2

Table (1) : R=S-2=11-2= R=9

12-2=10=»R=10

13-2=11=»R=11

14-2=12=»R=12

15-2=13=»R=13

16-2=15=»R=14

likewise use equation B for the table (2)

the outputs must be 3,4,5,6,7,8

and 9
