nt proves how segments YZ and XW are related?
A. They have slopes that are opposite reciprocals of 1 and -1 and are therefore perpendicular
B. They have the same slope of 1 and are therefore parallel
C. They have slopes that are opposite reciprocals of 0 and undefined and are therefore perpendicular
D. They have the same slope of -1 and are therefore parallel

Answer:

  D. They have the same slope of -1 and are therefore parallel

Step-by-step explanation:

In the linear equation ...

   ax + by = c

the slope of the line is m = -a/b. For the given equations, the slopes are ...

  x+y = 7   ⇒   m = -1/1 = -1

  x+y = 3   ⇒   m = -1/1 = -1

The slopes are the same, and both slopes are -1, so the lines are parallel.

The graph below shows the speed of a car that is driven through a town and then on a major highway. During which of the followin
Varvara68 [4.7K]

Considering the graph of the velocity of the car, it is found that the interval in which it was stopped at a traffic light was:

Between 3 and 4 minutes.

<h3>When is a car stopped at a traffic light?</h3>

When a car is stopped at a traffic light, the car is not moving, that is, it's velocity is of zero.

In this problem, the graph gives the <u>velocity as a function of time</u>, and it is at zero between 3 and 4 minutes, hence the interval in which it was stopped at a traffic light was:

Between 3 and 4 minutes.

What is the equation of the line shown in this graph? <br><br>any links will be reported<br><br>​
Blizzard [7]

Answer:

y = 1

Step-by-step explanation:

Slope is written in the form y=mx+b. Where m is the slope and b is the y-intercept.

When there isn't a slope, as in the line is flat and it isn't moving up or down, you wouldn't write anything for it. You would just write y equals the y-intercept (y = b).

Likewise, if the y-intercept is at (0,0), then you'd only write y equals the slope (y = mx).

Hopefully this makes sense :)

Btw, I also answered in the main comments earlier, so you can check that out as well.

A rectangular package can be sent through the mail only if the sum of its length and girth is not more than 120". find the dimen
Bingel [31]
Knowing that a square gives the optimum area; 

120=s²
√120=s 
√2×2×2×5×3=s
2√2×3×5=s
2√30=s 

Therefore, the length should be ≈10.95" 

Hope I helped :)

Answer:

  (5, 1) or maybe (h, k)

Step-by-step explanation:

The given form has no letters other than the variable. The vertex in this vertex-form equation can be read from the expression as (5, 1).

In the generic vertex form ...

  f(x) = a(x -h)² +k

the letters (h, k) are used to represent the vertex.

__

You would need to consult your curriculum materials to see what letters your author uses for the vertex in vertex form.
