![]() If a truck can hold 450 boxes, how many trucks does he need to ship all the boxes? The correct answer is 5. Tom's company has to ship 1,944 boxes of shoes. ![]() In this instance, the output, referred to as the dependent variable, is the number of gallons g remaining in the pool, because the volume depends on the input variable d, or the number of days since the pool started to leak. The input of a function is referred to as the independent variable because the input can be any number. The question requires an understanding of dependent and independent variables within various formulas. Dependent and independent variables cannot be determined in this situation because the equation is linear. d is the dependent variable because it is being multiplied by the independent rate of 450.ĭ. g is the independent variable because it is what needs to be found.Ĭ. ![]() g is the dependent variable because the volume is dependent on the number of days d.ī. Which of the following statements is true?Ī. The equation g = 50,000 - 450d can be used to find the number of gallons g remaining in the pool after d days. It is leaking at a rate of 450 gallons per day. The pair (−1,1) does not satisfy Belinda's rule, sinceġ ≠ − (−1)^2 = −1 The community pool has a capacity of 50,000 gallons. The pair (−1,1) also satisfies Chandra's function rule. Since 1= −(−1) the pair (−1,1) satisfies Adam's function rule. This process must be repeated for both Belinda's function and for Chandra's function. Y= −x to verify whether or not the substitution gives the correct output. To find out whether or not Adam's function could be the rule for the given table, it is necessary to substitute each pair of values, (0,0) and (−1,1) into A function is a rule that establishes a relationship between two quantities: the input and the output. The question requires an understanding of the concept of function and its definition. Adam's, Belinda's, and Chandra's Option (B) is correct. Which of the three equations could be the function rule for the table?ĭ. Smythe has asked his students to come up with function rules for the following table of data.Īdam says that the function rule is y = −xīelinda says that the function rule is y = −x2Īnd Chandra says that the function rule is y=−x2−2x
