Elena-2011 [213]

Answer:

You would have 4 red marbles and 8 blue marbles since you didn't return the ones you took out to the bag.

Step-by-step explanation:

6 - 2 = 4

The 8 would stay the same

There for you would have 4 red marbles and 8 blue marbles left in the bag. Totalled you have 12 marbles in the bag and 2 out of the bag. (8 + 4 = 12)

Including the marbles in and out of the bag you have 14 marbles. The 12 inside the bag + the 2 outside of the bag = 14 marbles totalled.

What is the surface area of this design? Please show work!
choli [55]
There are 8 faces on the figure.
There are two of the same sides so we can multiply that by 2. That side equals 76 in. 76 x 2 = 152.
Then, there is another side that equals 4 x 4 which is 24.
Another side equals 4 x 6 which is 24.
Another one equals 6 x 6 which is 36.
Another side equals 6 x 6 which also equals 36.
Another side equals 10 x 6 which is 60.
The last side is 10 x 6 which equals 60.
Which should add up to 392 in. x^{2}

What is an equation of the line that passes through the points (2, -6)(2,−6) and (-1, 6)(−1,6)?
Crank

Answer:

y = -4x + 2

Step-by-step explanation:

To figure out the slope, plug the coordinates in the formula.

y2 - y1 / x2 - x1

= 6 - (-6) / -1 -2

= -4

Now you need to find the y-intercept, take the coordinates and plug them into your equation so far, which is y = -4x + b

y = -4x + b

-6 = -4(2) +b

-6 = -8 + b

2 = b
