Help! I don’t get this at all !
Oxana [17]

Answer:

Step-by-step explanation:

I want to start with a quick explanation of slope/ rate of change since you say you don't get it at all.  Basically it measures how fast something changes.  Or, in other words, if x changes by so much, y will change by a corresponding amount.

If you look at the graph of just y=x, you can see that as x changes by 1 so does y.  if you make it y=2x, will x=1 makes y=2, and x = 2 makes y = 4, so here it changes by 2.  You cans ee it keeps going in that manner.  Also notice these make straight lines, maybe not horizontal, but still straight diagonal lines.  This is important for a constant slope.

The way slope can be describes is "rise over run" also.  Which means you count how many you "rise" and divide it by how many you "run", or in other words how your y values change and your x values change.  Using y = -.5x this time let's see what we get using this rise over run idea.  It's usually easier to compute the "run" first, so let's say we move from 2 to 4.  That makes our run 2, keep that in mind.  the y values that correspond to this are -.5*2 = -1 and -.5*4 = -2 note we keep the negative signs here.  Now that we have the y values what are the change in them?  well to go from -1 to -2 is -1, so our change in y is -1.

As I started with the rise over run is change in y divided by change in x.  we found both of those so our slope is -1/2 so negative one half.  That's just an example to hopefully clear up any confusion about slope.

The first part of your question I'm not sure about.  Are any numbers given at all anywhere?  the y looks longer than x but we can't really say exactly how long.  We can tell the slope is negative at least, since it points downward going from left to right, but I don't think we can say what the exact rate of change (slope) is.

The second part uses the first so hard to say.  If you can find what the rate of change is the answer will basically be (delta y) = (rate of change)*(delta x) since rate of change = (delta y)/(delta x) since delta means "change in"

The third gives some numbers, but we would still need the rate of change.  I'll give the best answer I can.  I do want to say that putting slope into an equation will often be represented by the letter m.

Anyway, pretending we know what m is, the method to find the equation of y is to use the formula y - y1 = m(x - x1).  x1 and y1 are the coordinates of a point that you need.  And int he question they give you one.  So we will plug in.

y - y1 = m(x - x1)

y - (-2.5) = m(x - 1) Then distribute that m we're pretending we know

y - (-2.5) = mx - m Then get y by itself

y = mx - m - 2.5

So once you know m you can solve everything else.  If you can find something that says how long those red and blue lines are, or maybe the points they point from and to you can let me know.  Hopefully this helpped though.

Hey there, Delilah
What's it like in New York city?
I'm a thousand miles away
But, girl, tonight you look so pretty
Yes, you do
Time square can't shine as bright as you
I swear, it's true
Hey there, Delilah
Don't you worry about the distance
I'm right there if you get lonely
Give this song another listen
Close your eyes
Listen to my voice, it's my disguise
I'm by your side
Oh, it's what you do to me
Oh, it's what you do to me
Oh, it's what you do to me
Oh, it's what you do to me
What you do to me
Hey there, Delilah
I know times are gettin' hard
But just believe me, girl
Someday I'll pay the bills with this guitar
We'll have it good
We'll have the life we knew we would
My word is good
Hey there, Delilah
I've got so much left to say
If every simple song I wrote to you
Would take your breath away
I'd write it all
Even more in love with me you'd fall
We'd have it all
Oh, it's what you do to me
Oh, it's what you do to me
Oh, it's what you do to me
Oh, it's what you do to me
A thousand miles seems pretty far
But they've got planes and trains and cars
I'd walk to you if I had no other way
Our friends would all make fun of us
And we'll just laugh along because we know
That none of them have felt this way
Delilah, I can promise you
That by the time we get through
The world will never ever be the same
And you're to blame
Hey there, Delilah
You be good, and don't you miss me
Two more years and you'll be done with school
And I'll be makin' history like I do
You'll know it's all because of you
We can do whatever we want to
Hey there, Delilah, here's to you
This ones for you
Oh, it's what you do to me
Oh, it's what you do to me
Oh, it's what you do to me
Oh, it's what you do to me
What you do to me

Mara is building a set of shelves supported by a diagonal brace, as shown in the diagram. Answer the questions to decide whether
Kazeer [188]

Answer:

Step-by-step explanation:

1). Since, m∠1 + m∠2 = 180° [Supplementary angles]

   If m∠2 = 120°

   m∠1 + 120° = 180°

   m∠1 = 180° - 120°

   m∠1 = 60°

2). If a transversal intersects two parallel lines on the top and middle,

   ∠1 and ∠5 will be corresponding angles.

3). Since, m∠1 = m∠5 = 60° (Corresponding angles)

   Therefore, both the lines on top and middle will be parallel.

4). Since, m∠9 + m∠11 = 180° [Supplementary angles]

   If m∠11 = 120°

   m∠9 + 120° = 180°

   m∠9 = 60°

   Since, m∠1 = m∠9 = 60° [Corresponding angles]

   Therefore, both the lines on the top and bottom shelves will be parallel.

5). Since, m∠5 = m∠9 = 60° [Corresponding angles]

    Therefore, middle and bottom shelves will be parallel.
