Question 1 (Multiple Choice Worth 2 points)


(05.06)


A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, determine which system of inequality best explains whether the company can build 20 child bikes and 6 adult bikes in the week.


No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100

Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100

None of the above

Verified Answer :

  1. 4c + 6a < = 120
        4c + 4a < = 100
        if u sub in 20 for c and 6 for a, u will find that the answer is : No,because the bike order does not meet the restrictions of 4c + 6a < = 120 and 4c + 4a < = 100. 
    ==========================
    2. 2x + y < 10
        2x - 4y > 8
        answers are : E,F,G
    ==========================
    3. y < = -2x + 3
        y < = x + 3
    ==========================
    4. y > = -3x + 1
        y < = 1 / 2x + 3
        answer : Both lines are solid. 1 lines passes thru (-2,2) and (0,3), shaded below the line. Other line passes thru (0,1) and (1,-2) and is shaded above the line....I am not 100% sure on this one
    ==========================
    5.y < -3x + 3
       y < x + 2
       answer is (1,-5)
    ==========================
    6. y < = 2x - 2
        y > -x + 3
