Write two equations of lines in slope-intercept form that are parallel to the graph of the line in part i. y=1/2x+5explain why the equations of the lines in part i and part ii are parallel.

The two equations are    and                                                                                                                                                                              

Step-by-step explanation:

we have given that : Part I=   equation of line

slope intercept form is y=mx+c

the slope of the line Part I is m=1/2

taken another equation of line Part II=

whose slope of line Part II is m=1/2

since, both equation have same slope therefore these two equation  Part II and Part I are parallel

It is also shown by the graph attached.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
