15.it will take 88 minutes to add 16 seats.

It will take 104.5 minutes to add 19 seats.

Step-by-step explanation:

Let m represent number of minutes.

We have been given that an assembly line worker at Rob's Bicycle factory adds a seat to a bicycle to a rate of 2 seats in 11 minutes.

We will use proportions to solve our given problem.

To find the time taken to add 16 seats, we will  in our proportion as:

Therefore, it will take 88 minutes to add 16 seats.

To find the time taken to add 19 seats, we will  in our proportion as:

Therefore, it will take 104.5 minutes to add 19 seats

parallelogram has vertices at (4,4), (7,4), (5,2), and (2, 2). The parallelogram is translated 7 units down and reflected across the y-axis. What are the coordinates of the first point of its image (4,4)?​

Answers

Answer:

Step-by-step explanation:

So we move the parallelogram down 7 units and get the coordinates: (-3,4) (0,4) (-2,2) (-5,2)

Then the equation for reflecting across the y-axis is (x,y) ---> (-x,y) Then I think you can solve it from there. Just take the x points and make them the opposite charge.

9514 1404 393

Answer:

  -24

Step-by-step explanation:

We can simplify this to ...

  b^2 +3(b -b^2) -2a

  = b^2 +3b -3b^2 -2a

  = -2b^2 +3b -2a . . . . . . . simplified form

This can be made easier for evaluation by factoring out b.

  = (-2b +3)b -2a

Using the given values, this is

  = (-2(4) +3)(4) -2(2)

  = (-5)(4) -4

  = -24 . . . . value of the expression

what solution is -5m=8m-2

Answers

Answer:

m=2/13

Step-by-step explanation:

Given function:

-5m=8m-2

Subtract middle value from both side:

[tex]-5m-8m=8m-2-8m[/tex]

Combine like terms:

[tex]-13m=-2[/tex]

Divide both sides by the same term:

[tex]\frac{-13}{13}=\frac{-2}{-13}[/tex]

Divide the terms:

[tex]=\frac{2}{13}[/tex]

Therefore, m=2/13.

Can someone help me please PLEASE HELP!!!?!?!!!?!?what is 4 .5 + 1/2 ? I was climbing up a mountain-pathWith many things to do,Important business of my own,And other people's too,When I ran against a PrejudiceThat quite cut off the view.My work was such as could not wait,My path quite clearly showed,My strength and time were limited,I carried quite a load;And there that hulking PrejudiceSat all across the road.So I spoke to him politely,For he was huge and high,And begged that he would move a bitAnd let me travel by.He smiled, but as for moving! He didn't even try.And then I reasoned quietlyWith that colossal mule:My time was short no other path The mountain winds were cool.I argued like a Solomon;He sat there like a fool.Then I flew into a passion,and I danced and howled and swore.I pelted and belabored himTill I was stiff and sore;He got as mad as I did But he sat there as before.And then I begged him on my knees;I might be kneeling stillIf so I hoped to move that massOf obdurate ill-will As well invite the monumentTo vacate Bunker Hill!So I sat before him helpless,In an ecstasy of woe The mountain mists were rising fast,The sun was sinking slow When a sudden inspiration came,As sudden winds do blow.I took my hat, I took my stick,My load I settled fair,I approached that awful incubusWith an absent-minded air And I walked directly through him,As if he wasn't there!
