Describe the difference between parallel and perpendicular lines, their slopes and graphs

Parallel lines have the same slopes (but different y intercepts). Parallel lines never cross. Parallel lines are the same distance from each other no matter where you are on either line. Think of it like a pair of perfectly straight railroad tracks.

-------------------------------------------------------------------------------------

Perpendicular lines cross at one point. The two lines form a 90 degree angle. The two slopes multiply to -1, which is another way of saying that the slopes are negative reciprocals of one another. For example, a line with a slope of 2/3 and another line with a slope of -3/2 has these two values multiply to -1; therefore showing they are perpendicular lines.

To provide a short definition,

Parallel lines are lines as the word suggests "parallel" which means they will stay side by side and never cross.

Perpendicular lines are lines that cross, usually to determine perpendicular lines you would take a slope and negatively reciprocate it.

<u>Perpendicular:</u>

1/2 -> -2

<u>Parallel:</u>

What two numbers multiply and get 100 and add and get -29??
butalik [34]
X, y - the numbers

The numbers multiply to 100.
xy=100

The numbers add up to -29.
x+y=-29 \\&#10;y=-x-29

Substitute -x-29 for y in the first equation:
x(-x-29)=100 \\&#10;-x^2-29x=100 \\&#10;-x^2-29x-100=0 \\&#10;-x^2-4x-25x-100=0 \\&#10;-x(x+4)-25(x+4)=0 \\&#10;(-x-25)(x+4)=0 \\&#10;-x-25=0 \ \lor \ x+4=0 \\&#10;x=-25 \ \lor \ x=-4 \\ \\&#10;y=-x-29 \\&#10;y=-(-25)-29 \ \lor \ y=-(-4)-29 \\&#10;y=25-29 \ \lor \ y=4-29 \\&#10;y=-4 \ \lor \ y=-25 \\ \\&#10;(x,y)=(-25,-4) \hbox{ or } (x,y)=(-4,-25)

The numbers are -4 and -25.

Select any equations that have the same solution set as:
aliya0001 [1]

Answer: 6+4x=26, 4x=20

Step-by-step explanation: 6+4x=20 is the initial equation but completely multiplied by two, so you can know without solving that it is equivalent.

If you solve the equation, 2x+3=13 (subtract 3 from both sides)

2x=10 (divide both sides by 2)

x equals 5.

if you plug in 5 as x to 4x=20, you get 20=20, which is a true statement, so this choice is also correct. You could also solve to prove x equals 5 in this equation as well. Divide 20 by 4 and you get x=5.

Solve the inequality. 1/5+1/3x&gt;1/2x-1/4
natita [175]

1/5 + 1/3·x > 1/2·x - 1/4

1/3·x - 1/2·x > - 1/4 - 1/5

2/6·x - 3/6·x > - 5/20 - 4/20

- 1/6·x > - 9/20

1/6·x < 9/20

x < 54/20

x < 27/10

x < 2.7

Alex787 [66]
Get a common denominator first.

90/130 becomes 1080/1560
Subtract the two and you get 77/1560
