ted wrote the following ruleand exspresion to represent the relationship between a and b in the input/output table
input a 9 15 21 24 36
output b 7 9 11 12 16
what did ted forget to do when he wrote the rule and exspresion
write the correct rule and exspresion
Based on the given input/output table, we can observe the following relationship between `a` and `b`:
When `a` is 9, `b` is 7.
When `a` is 15, `b` is 9.
When `a` is 21, `b` is 11.
When `a` is 24, `b` is 12.
When `a` is 36, `b` is 16.
Ted forgot to mention the pattern or the mathematical operation that governs the relationship between `a` and `b`. To find the correct rule and expression, let's analyze the pattern:
From `a` to `b`, we can see that the output `b` is always one less than half of the input `a`. In other words, `b` is equal to `(a/2) - 1`.
Hence, the correct rule and expression to represent the relationship between `a` and `b` would be:
Rule: Divide `a` by 2 and subtract 1.
Expression: b = (a/2) - 1.
