Will give first answer the ! picture below solve the system of equations below by graphing both equations with a pencil and paper. what is the solution? a. (4, 5) b. (2, 3) c. (–2, 1) d. (–4, –3)

For this one, plug in your x and y intercepts for the corresponding letters and see which one is true.  I always start with the first equation and then see which ones solve it first, that will cut your time down on a test.

Lets start with A. (4,5)

and the first equation y=x+1

5=4+1, which is true so A is a potential answer

B. (2,3)

3=2+1, B is a potential as well

C. (-2,1)

1=-2+1, which is false so C is out

D. (-4,-3)

-3=-4+1, which is true.

To cut down on time, do the same thing with the second equation and your final answer will be A. (4,5)

this is answer of 144 cubic meters

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
