A flow diagram shows a rule. If the input is x and the output is y, the rule is "x times 9, then add 8". Complete the input/output values.

Here are the solutions to the questions based on the flow diagram:

Step 1: Determine the rule and complete the input/output values.
The flow diagram shows a rule: "$\times 9$" then "$+ 8$". We will use this rule for calculations.
Let the input be $x$ and the output be $y$. The rule is $y = (x \times 9) + 8$.

• Finding the missing input value: One output value is given as 17, with a missing input. $$(x \times 9) + 8 = 17$$ $$x \times 9 = 17 - 8$$
