The car costs $7500
7500-3000=4500 to be paid in monthly payments
4500/36=125
Ryan paid 125 per month

3000+36x= 7500
-3000          -3000

= 36x= 4500 
= /36     /36
x= $125

Which graph represents an equation in the form =?<br><br> Please help me!!
Genrish500 [490]

That's a question about graphs.

In the Cartesian coordinate system, we have two axes: The x-axis (horizontal) and the y-axis (vertical).

When we want to represent a equation in the cartesian coodinate system, we associate a point in the x-axis and other in the y-axis. The Cartesian coordinate is represented by (x, y).

To represent some equation in a graph, we need at least two points to draw a line that cross these 2 points.

For example: To represent the equation y  = x +1, let's replace the value of <em>x</em>:

  • When<em> x = 0</em> → y = 0 + 1 = 1. Therefore, the coordenate is (0, 1).
  • When <em>x = 1</em> → y = 1 + 1 = 2. Therefore, the coordenate is (1, 2).

Finally, if we draw a line tha cross these 2 points, we will have the graph that represents y  = x +1.

Now you know about it, let's solve our problem?

In that question, we should to find the graph that represents the equation y = kx, but we don't know the value of <em>k</em>, so what should we do? It's easy:

<em>k </em>is a constant. That means that the value of k never changes. Now, let's analyze a specific case:

If <em>x = 0</em>, so <em>y = 0</em> as well. But why? We know that any number multiplied by 0 is equal 0. Therefore:

  • When If <em>x = 0 → </em>y = 0 \times k = 0. So, this graph cross the coordinate (0,0).

With the informations that the problem give to us, these are the unique things that we can find, but that's enough.

When we look at the options, just the second graph have a line that cross the coordenate (0, 0). Therefore, the correct answer is the graph below:

I hope I've helped. :D

If z varies directly with the product of x and y (z=kxy), then z is said to vary jointly with x and yThe area of a triangle vari
Zigmanuir [339]
The area of a triangle is  (1/2) * (base) * (height) .

It varies jointly with the length of the base and the height.

The constant of variation is the (1/2) .

If the least value of n is 4, which inequality best shows all the possible values of n?
Sladkaya [172]
Comment
If the least value of n is 4 that means that 4 is one of the numbers in whatever it is that you are describing. In other words n = 4 is part of your answer. If that is the case, the last two values are incorrect because 4 is not included in either one of them.

Discussion
So that means that you have to choose between one of the first 2. The key word is least. It means that the lowest possible value is 4. Nothing is lower. 

When you write something like n ≤ 4 what you are saying is the n must be = to or less than 4. The arrow head points to the smallest number which, in this case, is n. 

But the question says that the least number is 4. So the arrowhead must point towards the 4. This we have that n must be larger than 4. 

Conditions
There are 2 conditions to this problem
n must be greater than 4
n can equal 4. It is the smallest number.

n≥4 <<<<<answer
B <<<<<< answer.
