Since 8 is 1/3 of 24 we can multiply 16x-2y to get 48x-6y, now we can see the two equations equal to each other. So 48x-6y= 4x+5y and you combine like variables by doing the inverse operation so you’ll get 44x= 11y. Simplified, this is 4x= y. So, now you plug in 4x for the y variable in the first equation, so you’ll get 16x- 2(4x)= -8. Then you solve for x...
16x- 8x= -8
8x= -8
x= -1

Then you plug the -1 in for the x variable and then solve... so
16(-1)- 2y= -8
-16- 2y= -8
-2y= 8
y= -4

So, overall your answer will be x= -1, y= -4

Amy's penny bank is 1/2 full. After she adds 360 pennies, it is 5/6 full. How many pennies can Amy's bank hold?
stellarik [79]

Answer:

1,080 Pennies

Step-by-step explanation:

This question is fairly simple, you just have to simplify it. You are starting at already half-full, so you can keep that 1/2 in mind. Then, she adds 360 pennies to get 5/6. If you convert 1/2 into 3/6, you can see that 360 pennies fills 2/6 of the piggy bank. So now you can solve two different ways. The first, you can take 360 and multiply it by 3 to get the amount that can fit in the piggy bank, because 2 * 3 = 6 and that would make it 6/6, or 1. The other way would be to divide 360 by 2 to get 1/6 of the piggy bank, or 180. Then you can multiply 180 by 6 to get the entire amount.

Hope this helped ^-^

Answer:

  A'(-4, -4), B'(6, -4), parallel

Step-by-step explanation:

The dilation factor multiplies each of the coordinate values. The line that was y=-2 becomes the line y=-4, a parallel horizontal line.
