Answer:

<u><em>x = -1</em></u>

Step-by-step explanation:

Isolate the variable by adding 7 on both sides. 5x-7+7 is 5x, and -12+7 is -5. Then, you get the equation 5x = -5. You have to then divide by 5 on both sides. 5x/5 is x and -5/5 is -1. You would then get that x = -1.

Answer:

c ln (x^3/y^3)

Step-by-step explanation:

3 ln x - 3 lny

We know that a ln b = ln b^a

ln x^3 - ln y^3

We also know ln a - ln b = ln (a/b)

ln (x^3/y^3)

Use slopes and y-intercepts to determine if the lines 5x-5y=-2 and -x+2y=4
HACTEHA [7]

The given pair of lines are not perpendicular.

<h3>What is a line?</h3>

The line is a curve showing the shortest distance between 2 points.

5x - 5y = -2 - - - - - (1)
Transform the equation into standard form,
5x + 2 = 5y
y = 5x /5 + 2/5
y = x + 2/5


The slope of equation 1 is m_1 = 1  and intercept c = 2 / 5


Similarly
x + 2y = 4    - - - - - - - -(2)
Transform it into standard form
y = -x/2 + 4 /2
y = -x / 2 + 2


Slope of the equation 2  m_2= -1 / 2 and intercept c = 2
Slope of line 1 * slope of line 2 = 1 * -1/2 = -1/2


Since the lines are not perpendicular because the pair of lines does not satisfy the property of perpendicular lines i.e
m_1*m_2 = -1

Thus, the given pair of lines are not perpendicular.
