4. One type of scale that measures weight is called a spring scale. A spring hangs from a fixed position. A weight. can be attached at the bottom (see the hook on the example pictured at the right). The weight causes the spring to stretch, and the new length of the spring tells you how heavy the weight is. A function can describe the length of the spring based on the amount of weight. The function equation for a certain spring scale is where x is the weight in grams and y is the length of the spring in centimeters. a. b. y=0.5x+10 Complete the table of values for this function. y 2 5 Original material under copyright, 2012 8 17 Problem adapted from Elementary Algebra by Harold Jacobs Evaluate 0.5x+10 when x=7.
