SECTION B: Problem Solving – Interpreting Relationships 1.1 Determine the input if the output is 20. Given the rule: y = 2x + 4 Given the output: y = 20 Step 1: Substitute the output value into the rule. 20 = 2x + 4 Step 2: Subtract 4 from both sides of the equation. 20 - 4 = 2x 16 = 2x Step 3: Divide both sides by 2 to solve for x. (16)/(2) = x x = 8 The input is 8. 1.2 Explain in words what the rule 2x + 4 means. The rule 2x + 4 means to multiply a number by 2 and then add 4 to the result. 3 done, 2 left today.
