5x+15y=12 ordered pair are solution to the equation
gayaneshka [121]

Let's solve for x.

5x+15y=12

Step 1: Add -15y to both sides.

5x+15y+−15y=12+−15y

5x=−15y+12

Step 2: Divide both sides by 5.

5x

5

=

−15y+12

x=−3y+

Answer:

x=−3y+12/5

Let's solve for y.

5x+15y=12

Step 1: Add -5x to both sides.

5x+15y+−5x=12+−5x

15y=−5x+12

Step 2: Divide both sides by 15.

15y

15

=

−5x+12

What is the quotient of -8(^6)/4x(^-3)
Anna [14]

For this case we must find the quotient of the following expression:

\frac {-8x ^ 6} {4x ^ {- 3}} =

By definition of power properties we have:

a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}

Rewriting the expression we have:

\frac{-8}{4}*x^6*x^3

By definition of multiplication of powers of the same base we have to put the same base and add the exponents:

-2x^{6+3}

Answer:

-2x ^ 9
