- 13.The length s (in inches) of a spring is a function of the weight w (in pounds) that is attached to the spring. The length of two springs, as a function of the weight added ares = 50 + 3w ands = 10 + 8wFor the FIRST equation, what does "50" tell you about the length of the spring?
- A.
50 is how much the spring stretches with every pound added

- B.
50 is the y-intercept

- C.
50 is the length of the spring with no weight attached

- 14.The length s (in inches) of a spring is a function of the weight w (in pounds) that is attached to the spring. The length of two springs, as a function of the weight added ares = 50 + 3w ands = 10 + 8wFor the SECOND equation, what does "8" tell you about the length of the spring?
- A.
8 is how much the spring stretches by with every pound added

- B.
8 is the slope

- C.
8 is the length of the spring with no weight attached

- 15.The length s (in inches) of a spring is a function of the weight w (in pounds) that is attached to the spring. The length of two springs, as a function of the weight added ares = 50 + 3w ands = 10 + 8wFind the weight "w" that makes the length of these springs equal
- 16.The length s (in inches) of a spring is a function of the weight w (in pounds) that is attached to the spring. The length of two springs, as a function of the weight added ares = 50 + 3w ands = 10 + 8wUsing the last question/answer, find the length "s" of the two equal springs
