Lines MN and PQ are parallel. Lines RS and TV intersect them. On a coordinate plane, 3 lines are shown. Line M N has points (neg

ative 3, negative 1) and (3, 3). Line P Q has points (negative 3, negative 4) and (3, 0.5). Line R S has points (negative 2, 4) and (2, negative 2). Which statements are true about these lines? Select three options. The slope of line MN is Two-thirds. The slope of line PQ is undefined. The slope of line RS is Negative three-halves. Lines RS and TV are parallel. Line RS is perpendicular to both line MN and line PQ.

Answer:

The slope of line MN is two thirds,

The slope of line RS is negative three-halves

and line RS is perpendicular to both line MN and PQ

Step-by-step explanation:

For the first two, I found the slope using the slope formula, and I know the third one is correct because that is what it says in the very beginning.

Hope this helped, sorry if it is a little hard to understand, it was pretty hard to understand. :)

Does a two-digit number exist such that the digits sum to 9 and when the digits are reversed the resulting number is 9 greater t
Alexeev081 [22]

The answer would be "t + u = 9 and 10t + u = 10u + t - 9". This can be found if you replaced t with 4 and u with 5. Adding the 2 digits would give you 9, and using the formula "10t + u = 10u + t - 9". Replace t and u with 4 and 5 then simplify. 10*4 + 5 = 10*5 + 4 - 9. Simplifying you'd get 45 = 54 - 9 or 45 = 45 which make the statement true. Thus making "t + u = 9 and 10t + u = 10u + t - 9" the answer.

I hope this helps!

To snails are 189 cm apart. They crawl towards each other at rates that differ by 1 cm a minute. After 27 minutes they meet. How
Stella [2.4K]

Speed of snail 1 = 3.795 cm/minute

Speed of snail 2 = 4.795 cm/minute

<em><u>Solution:</u></em>

Given that,

Total distance = 189 cm

They crawl towards each other at rates that differ by 1 cm a minute

Let the speed of snail 1 be "x"

Let the speed of snail 2 be "x + 1"

Total time = 22 minutes

Since the snails are moving towards each other,

Speed = x + x + 1 = 2x + 1

<em><u>How fast is each snail crawling?</u></em>

Distance = speed \times time\\\\189 = 2x + 1 \times 22\\\\189 = 44x + 22\\\\44x = 189 - 22\\\\44x = 167\\\\x = 3.795

Thus,

Speed of snail 1 = 3.795 cm/minute

Speed of snail 2 = 3.795 + 1 = 4.795 cm/minute
