Dilbert invests a total of $33 000 in two accounts paying 6% and 10\% interest, respectively. How much was invested in each acco
vladimir1956 [14]

Answer:

In the 6% account, 13,000 was deposited

In the 10% account, 20,000 was deposited

Step-by-step explanation:

Here, we are interested in calculating how much invested in each account

.

Let the amount invested be $x and $y

Mathematically;

x + y = 33,000 ••••(i)

Now let’s work with interest

6% of x + 10% of y = 2780

6/100 * x + 10/100 * y = 2780

Multiply through by 100

6x + 10y = 278000 •••••••••(ii)

From i, x = 33,000 -y

Put this into ii

6(33,000 -y) + 10y = 278000

198,000-6y + 10y = 278000

4y = 80000

y = 80,000/4 = 20,000

But x = 33,000 -y = 33,000 -20,000 = 13,000

(PLEASE HELP 15 POINTS I HAVE 7 MINS) explain your awnser what are the x- and the y-interceptions of 3x - 2y = 18
S_A_V [24]

The given equation is

3x-2y=18

x intercept

To find the x intercept, we have to plug 0 for y and solve for x.That is

3x-2(0)=18&#10;\\&#10;3x=18&#10;\\&#10;x=6

So x intercept is (6,0) .

y intercept

To find the y intercept , we have to plug 0 for x and solve for y. That is

3(0)-2y=18&#10;\\&#10;-2y=18&#10;\\&#10;y=-9

So the y intercept is (0,-9) .
