Ket [755]

Answer:

The money invested in the account 1 was $8,000 and in the account 2 was 12,000.

Step-by-step explanation:

In this case we can formulate a system of equations that could find the amount invested in each account, this is:

Money invested in the account 1 is A

Money invested in the account 2 is B

Eq. 1: A+B=20,000

Eq. 2: \frac{6}{100} *A+\frac{8}{100} *B=1,440

Replacing the equation 1 in 2, this is:

\frac{6}{100} *(20,000-B)+\frac{8}{100} *B=1,440

1,200-0.06B+0.08B=1,440

0.02B=1,440-1,200

B=\frac{240}{0.02}

B=12,000

Now, we can find A:

A=20,000-B

A=20,000-12,000

A=8,000

The money invested in the account 1 was $8,000 and in the account 2 was 12,000.

Y-1=5/6(x-4) in standard form
scoray [572]
           y - 1 = ⁵/₆(x - 4)
           y - 1 = ⁵/₆(x) - ⁵/₆(4)
           y - 1 = ⁵/₆x - 3¹/₃
             + 1         + 1
                 y = ⁵/₆x - 2¹/₃
        ⁻⁵/₆x + y = ⁵/₆x - ⁵/₆x - 2¹/₃
   -6(⁻⁵/₆x + y) = -6(-2¹/₃)
-6(⁻⁵/₆x) - 6(y) = 14
         5x - 6y = 14
