  • 7. 

    y = 700 - 0.5xy = 900 - 1xSolve for x

    Explanation
    700 - 0.5x = 900 - 1x
    700 + 0.5x = 900
    0.5x = 200
    x = 400

    Rate this question:

  • 8. 

    y = 700 - 0.5xy = 900 - 1xUse the previous question/answer to solve for y

    Explanation
    y = 700 - 0.5(400)
    y = 700 - 200
    y = 500

    or

    y = 900 - 1(400)
    y = 900 - 400
    y = 500

    Rate this question:

  • 9. 

    y = 34x - 29y = 13x + 13Solve for x

    Explanation
    34x - 29 = 13x + 13
    21x - 29 = 13
    21x = 42
    x = 2

    Rate this question:

  • 10. 

    y = 34x - 29y = 13x + 13Use the previous question/answer to solve for y

    Explanation
    y = 34(2) - 29
    y = 68 - 29
    y = 39

    or

    y = 13(2) + 13
    y = 26 + 13
    y = 39

    Rate this question:

  • 11. 

    h = 2t - 6h = 15 + 0.25tSolve for t

    Explanation
    2t - 6 = 15 + 0.25t
    1.75t - 6 = 15
    1.75t = 21
    t = 12

    Rate this question:

  • 12. 

    h = 2t - 6h = 15 + 0.25tUse the previous question/answer to solve for h

    Explanation
    h = 2(12) - 6
    h = 24 - 6
    h = 18

    or

    h = 15 + 0.25(12)
    h = 15 + 3
    h = 18

  • 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

    Correct Answer
    C. 50 is the length of the spring with no weight attached
    Explanation
    The correct answer is "50 is the length of the spring with no weight attached". This means that when there is no weight attached to the spring, its length is 50 inches.

    Rate this question:

  • 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

    Correct Answer
    A. 8 is how much the spring stretches by with every pound added
    Explanation
    The correct answer is "8 is how much the spring stretches by with every pound added." This means that for every pound of weight added to the spring, the length of the spring increases by 8 inches.

    Rate this question:

  • 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

    Correct Answer
    8
    Explanation
    50 + 3w = 10 + 8w
    50 = 10 + 5w
    40 = 5w
    w = 8

    Rate this question:

  • 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

    Correct Answer
    74
    Explanation
    s = 50 + 3(8)
    s = 50 + 24
    s = 74

    or

    s = 10 + 8(8)
    s = 10 + 64
    s = 74
