Kx + 3x = 4 solve for x.

1 answer:

4 0

Take out a common factor between 3x and kx. That means use the distributive law to get what you normally would start with.

x(k + 3) = 4

Now divide by k + 3

x = 4/(k + 3)

That's as much as you can do with this question.

The line x − y = 2 is on a coordinate plane and contains EF, which is one side of square EFGH. What is the slope of the line tha

Alborosie

Answer:

The slope of FG is -1

Step-by-step explanation:

Given

Square EFGH

EF: $x - y = 2$

Required

Determine the slope of FG

First, we calculate the slope of EF

$x - y = 2$

Make y the subject

$-y = 2 - x$

$y = x -2$

The general equation has the form: $y = mx + b$

Where

$m = slope$

Compare $y = mx + b$ to $y = x -2$

$m = 1$

From the name of the square EFGH, we can conclude that EF and FG are perpendicular

The relationship between perpendicular lines is:

$m_2 = -\frac{1}{m_1}$

Where

$m_1 = m = 1$ -- Slope of EF

and

m2 = slope of FG

Substitute 1 for m1 in $m_2 = -\frac{1}{m_1}$

$m_2 = -\frac{1}{1}$

$m_2 = -1\\$

Hence, the slope of FG is -1

If you are looking for an expression it would be x < 4 and the < has a line underneath for less than or equal to. If this is right could I possibly have brainliest? Hope this helped!! :)
