Answer:

x = -2

Step-by-step explanation:

3x+2=−4

3x+2−2=−4−2(Subtract 2 from both sides)

3x=−6

3x /3 = −6 /3

(Divide both sides by 3)

x=−2

Is each line parallel, perpendicular, or neither parallel nor perpendicular to the line −3x+5y=−15? Drag and drop each choice in

nexus9112 [7]

The first line is perpendicular, the second line is not perpendicular and not parallel , the third line is parallel to the above line and the forth line not parallel or perpendicular to the line.

<h3>How can the slope of the line be calculate?</h3>

The slope of the line is been given as −3x+5y=−15

Then $y= \frac{3}{5x} -3$ , hence the slope is $\frac{3}{5}$

Slope of the first line 5x + 3y = 15 after calculation is

the slope is $y= \frac{5}{-3x} +5\\\\\frac{5}{-3}$

this means that the line is perpendicular to the given line

Slope of the second line 3x + 5y = 15 after calculation is

$y= \frac{3}{-5x} +15\\\\\frac{3}{-5}$

This means that the line is not perpendicular and not parallel

Slope of the Third line -3x + 5y = 15 can be calculated as

$y= \frac{3}{5x} +15\\\\\frac{3}{5}$

This means that the line is parallel to the above line.

Slope of the first line 3x + 5y = 15 after calculation is

$y= \frac{-3}{5x} +3\\\\\frac{-3}{5}$

This means that the line is not parallel or perpendicular to the line
