Answer:

$960 into 6% account and $1600 into 8% account

Step-by-step explanation:

Let money put in 6% account be x

let money put in 8% account be y

How much interest did she earn?

2560 * 0.0725 = $185.6

Now, we can write:

0.06x + 0.08y = 185.6

and we know

x + y = 2560

We can say:

x = 2560 - y

and we put this into 1st equation:

0.06(2560 - y) + 0.08y = 185.6

153.6 - 0.06y + 0.08y = 185.6

0.02y = 32

y = 1600

and thus, x = 2560 - 1600 = 960

She put $960 into 6% account and $1600 into 8% account

Is (6,-10) a solution of y=3x-8
Vitek1552 [10]
You can easily test this if you know that (6, -10) corresponds to (X, Y). Knowing this, you can: 

X = 6
Y = -10

you put this into your equation:

-10 = 3*6 - 8

calculate it:

-10 = 18 - 8
-10 = 10
This is not true of course, -10 is not equal to 10. Therefore, (6, -10) is not a solution of y = 3x-8 :)
