Solve the problem.
-To estimate the ideal minimum weight of a woman in pounds multiply her height in inches by 4 and subtract 130. Let W = the ideal minimum weight and h = height. Express W as a linear function of h.
A) W(h) = 4h - 130
B) W(h) = 130h + 4
C) W(h) = 130
D) W(h) = 4 (h + 130)

Question

Quizplus · Accepted Answer

The problem states to multiply the height by 4 and subtract 130, which is expressed mathematically as 4h - 130. Therefore, the linear function for minimum ideal weight is W(h) = 4h - 130. The problem states that to find the ideal weight (W) of a woman, we need to multiply her height (h) by 4 and subtract 130. This can be written as W(h) = 4h - 130, which is a linear function of h. Option A is the only choice that reflects this equation. Option B has the incorrect coefficient of h and a constant term that doesn't make sense in this context. Option C is a constant function and doesn't involve h at all. Option D adds 130 to 4h, which is the opposite of what we need to do. Therefore, the correct answer is A.
