We are given relation between distance( in kilometers) travelled and number of hours taken by an Albatross bird.
Distance in kilometers taken by variable d.
Number of hours by t.
And situation is given d=50t.
We know, direct relation formula y= kx read as y is directly proportional to x. And k is the constants of proportionality.
In the given fuction y is taken by variable d and x is taken by variable t.
If we compare d=50t by y = mx, the value of k is 50.
Therefore, constant of proportionality is 50.
Constant is a number that never change it's value.
Therefore, constant of proportionality is just 50.
But we can say variables d and t are two variables those are directly proportional to each other.
Constant of proportionality is actually unit rate of change.
For the given situation constant of proportionality is the number of km travelled in per unit time (in 1 hour.)
If we divide 400km 8 hours, we get 400/8 = 50 km per hour.
Therefore, variables of proporation are d and t and relation between them is " they are directly proportional to each other".
And the constants of proportionality is just 50.

Which classification best describes the following system of equations? 3x+6y-12z=36 x=2y-4z=12 4x+8y-16z=48 inconsistent and dep
Viktor [21]

<u>Answer:</u>

Consistent and dependent

<u>Step-by-step explanation:</u>

We are given the following equation:

1. 3x+6y-12z=36

2. x+2y-4z=12

3. 4x+8y-16z=48

For equation 1 and 3, if we take out the common factor (3 and 4 respectively) out of it then we are left with x+2y-4z=12 which is the same as the equation number 2.

There is at least one set of the values for the unknowns that satisfies every equation in the system and since there is one solution for each of these equations, this system of equations is consistent and dependent.

Hello,
Damm [24]

Answer:

  -1

Step-by-step explanation:

The axes on your graph are not labeled, so we have to assume they follow the usual convention. That is, the vertical axis is the y-axis, and the horizontal axis is the x-axis.

The x-coordinate tells how far to the left or right of the y-axis the point is. Here, point L is 1 grid square to the left of the vertical line that is the y-axis. If you follow the vertical line through L down to where it crosses the x-axis, you will see an unlabeled open circle there. (We don't know the purpose of that circle, but we call it to your attention so you know you're looking in the right place.)

Looking 4 more grid squares to the left of that point, you see the marking "-5". This tells you each grid square corresponds to one unit. Then the first one to the left of the y-axis (where the open circle is) has a value of -1. That is the value of the x-coordinate of point L.

The x-coordinate of point L is -1.
