Answer:

-4/3

Step-by-step explanation:

You can use rise/run. The rise (y values) goes from 5 to -3. You subtract 8 for this. The run (x values) goes from 2 to 8. You add 6 for this. the proportion is -8/6, which can be simplified to -4/3.

Therefore, the slope is -4/3!

Hope I helped!!!!!!

Which expression is equivalent to sqrt128x^5y^6/2x^7y^5 ? Assume x 0 and y > 0.
kolbaska11 [484]

<u>Answer:</u>

\frac{8\sqrt{y} }{x}

<u>Step-by-step explanation:</u>

We are given the following expression and we are to simplify it:

\sqrt {\frac {128x^5y^6} {2x^7y^5} }

To make it easier to solve, we can also write this expression as:

\sqrt {\frac{128}{2} * \frac {x^5} {x^7} * \frac {y^6} {y^5}}

Now we will cancel out the like terms to get:

\sqrt {64*\frac{1} {x^2}*y }

Taking the square root of the terms to get:

8*\frac {1}{x} .\sqrt{y}

\frac{8\sqrt{y} }{x}

Solve the following system using substitution.
ziro4ka [17]

Answer/Step-by-step explanation:

3. By substitution method, let's substitute \frac{2}{3}x- 4 for y in the first equation.

Thus,

\frac{1}{3}x + 2(\frac{2}{3}x- 4) = 1

Solve for x

\frac{x}{3} + \frac{4x}{3} - 4 = 1

Add 4 to both sides

\frac{x}{3} + \frac{4x}{3} - 4 + 4 = 1 + 4

\frac{x}{3} + \frac{4x}{3} = 5

\frac{x + 4x}{3} = 5

\frac{5x}{3} = 5

Multiply both sides by 3

\frac{5x}{3}*3 = 5*3

5x = 15

Divide both sides by 5

x = 3

Now, substitute 3 for x in the equation.

y = \frac{2}{3}x- 4

y = \frac{2}{3}(3) - 4

y = 2 - 4

y = -2

The solution of the equation is x = 3, y = -2

4. Solving by elimination, let's try to eliminate the x-variable by adding both equation together.

3x - 2y = 11

-3x - y = 4

            -3y = 15  => (-3x +(-3x) = 0; -2y +(-y) = -3y; 11 + 4 = 15)

Divide both sides by -3 to solve for y

\frac{-3y}{-3} = \frac{15}{-3}

y = -5

Substitute -5 for y in the first equation to find x

3x - 2(-5) = 11

3x + 10 = 11

Subtract 10 from both sides

3x + 10 - 10 = 11 - 10

3x = 1

Divide both sides by 3

\frac{3x}{3} = \frac{1}{3}

x = \frac{1}{3}

The solution is x = \frac{1}{3}, y = -5
