determine the slope of two consecutive sides are parallel, perpendicular or neither(-1,2) (4,4) (2,-1) (-3,-3)

PtichkaEL [24]

Answer: parallel

Step-by-step explanation:

Given the following coordinate

(-1,2) (4,4) and (2,-1) (-3,-3)

Two parallel lines will surely have the same slope. While the product of the two perpendicular lines will be equal to negative one.

Let's find the slope of the coordinate.

Slope m can be expressed as

M = (Y2 -Y1)/( X2 - X1)

For coordinate (-1,2) (4,4)

Slope m = ( 4 - 2 ) / (4 + 1)

Slope m = 2/5

For coordinate (2,-1) (-3,-3)

Slope m = ( -3 +1 ) / ( -3 -2 )

Slope m = -2/ -5

Slope m = 2/5

Since the two slope are the same, we can conclude that the two lines are parallel to each other.

Twice a number decreased by 8 by 12 is 2 less than half the number what is the number?

natali 33 [55]

Answer:
4
Step-by-step explanation:
with the information given, we can express the equation:

where is the unknown number?
to clear for first we multiply the equation by 2, to eliminate the fraction:

moving all terms with to the left:

and adding +16 to each side:

and finally, dividing by 3

the number is 4.

A runner covers the last straight stretch of a race in 3 s. During that time, he speeds up from 5 m/s to 11 m/s.What is the runn

nikitadnepr [17]

Answer:

From first Newton's equation of motion:

${ \bf{v = u + at}}$

Substitute the variables:

${ \tt{11 = 5 + (a \times 3)}} \\ { \tt{3a = 6}} \\ { \tt{a = 2 \: {ms}^{ - 2} }}$

Acceleration is 2 ms-²

ASAP! Due tomorrow! 25 points! Read the word problem. Write an equation to represent the word problem. Solve the equation. Durin

Marrrta [24]

What you gotta take from this problem:

What Joe got during break = $2t+2$

What his sister gave him = $3t$

What he has total = 10 tadpoles.

Now to assemble this equation:

$2t+2+3t=10$

Now combine like terms to get $5t+2=10$

Subtract 2 on each side of the equation to get $5t=8$

Now you would divide 5 on each side and get $t=1.6$ , however since you can't have a .6 of a tadpole, you would have to round it up to 2.

Which two pairs of numbers have cubes that add up to 1729? because there are two pairs of numbers to find, you should select a t

qwelly [4]

It is called the hardy Ramanujan's number, named after the Indian mathematician, Srinivasa Ramanujan, and British Mathematician G. H Hardy.
Hardy went to visit Ramanujan while he was ill. He noticed that the number of the taxi he went in was 1729, which he thought was a dull number.

1729 = 12³ + 1³
1729 = 10³ + 9³

Fujiwara claimed that he proved there are only four numbers that have the property. Even though it seems to be true, he never has shown his proof. No other natural number, other than 1729, can be expressed as a sum of the cubes of two natural numbers in two different ways.
