Abicycle 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 10 child bikes and 12 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

Yes, because the bike order meets the restrictions of and  

Step-by-step explanation:

Let c represents the child bike

Let a represents the adult bike

Now Each child bike requires 4 hours to build

So, c child bike requires time to build = 4c

Each adult bike requires 6 hours to build

So, a adult bike requires time to build = 6a

We are also given that the company is able to have up to 120 hours of building time

So, the equation becomes:

 --1

Each child bike requires 4 hours to test

So, c child bike requires time to test = 4c

Each adult bike requires 4 hours to test

So, a adult bike requires time to test = 4a

We are also given that the company is able to have up to 100 hours of testing time for a week.

So, the equation becomes:

 --2

With 1 and 2

The system of equations represent the situation :

Now we are given that whether the company can build 10 child bikes and 12 adult bikes in the week.

So, substitute c =10 and a = 12 in both equations.

Equation 1:

Equation 2:

Thus the bike order meets the restrictions of and  

Thus Option C is correct : Yes, because the bike order meets the restrictions of and  

are you sure this is middle schools math? ?

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
