What is the solution of the system? Use elimination.

Note that if we add each side of the 2 equations, y will cancel out:

-12x-y+(17x+y)=6+4

5x=10

x=2


Substituting x=2 in either of the equations, we find the value of y.

Let's use the first equation:

-12x-y=6

-24-y=6

-y=24+6

-y=30, so y=-30.

Thus, the solution is (2, -30)

Answer: C

frosja888 [35]

Answer:

Event 2, Event 3, Event 4, Event 1

Step-by-step explanation:

The probability of Event 2 occurring is 0/12(0%) as there are no red marbles in the bag.

The probability of Event 3 occurring is 13/20(65%) as you will get an orange marble from Bag B 13 out of 20 times.

The probability of Event 4 occurring is 9/12(75%) as you will get a yellow marble from Bag A  9 out of 12 times.

The probability of Event 1 occurring is 20/20(100%); therefore you will always get either a yellow or an orange marble from Bag B.

This figure is dilated by a factor of 1 2 , with the origin as center. Which statement is NOT correct? A) R(2, 8) → R'(1, 4) B)
Anton [14]
Statement B would be the correct answer because the y's stayed the same. Having a dilation of 1/2 means that both the x and y from the original point will be multiplied by 1/2. Every other answer is multiplied by 1/2, meaning B is the correct answer. 

Hope this helps! If you need further assistance or explanation, message me or comment under this post!

I think B but was told C
olganol [36]

check the picture below.


notice 2002, is just a tiny drop from the red line, 2000 is hardly below 2002, so is also close to the red line, and 1998 is also.


now, 1996 is a tad farther than 1998.


to be fair, I'd say 2002, 2001 and 1998, but off all the provided sets, 1998, 2002 and 2000 works.
