Carletta and johnathan are entrepreneurs making mother boards for computers that are being manufactured by their friend, dewey sasser. carletta can make one mother board in 12 hours while it takes johnathan 16 hours to make one mother board. dewey suggested they could produce mother boards faster if they combined forces and worked together to build each mother board. what will be the time, in hours, that carletta and johnathan can build a mother board when working together? (round your answer to the nearest hour.)

Carletta and Johnathan can complete the work in 7 hours while working together.

Step-by-step explanation:

Carletta can make one mother board in 12 hours.

Johnathan can make one mother board in 16 hours.

Let the time taken together to complete the work be t.

And together they are doing '1' work.

So, together they can complete the work in :

LCM of 12 and 16 is 48

So, equation becomes:

t = 6.857 hours

And to the nearest hour it is 7 hours.

Therefore, Carletta and Johnathan can complete the work in 7 hours while working together.

you need to show the graph

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
