How do you find the ratio of x and y coordinates

Mathematics
1 answer:
Firdavs [7]2 years ago
6 0

Answer:

(in step-by-step explanation)

Step-by-step explanation:

The ratio x:y is the same as the fraction x/y  if that helps, so it is basically putting the coordinates into a fraction. Here is a video that might help also: https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-ratios-prop-topic/cc-6th-ratio-word-problems/v/ratios-on-coordinate-plane

Coordinate planes are a way of expressing data, so if it makes it easier, put the data into a ratio! Sorry, it is a bit difficult to explain such a broad question.

The formula for the area of a triangle is 1A bh2=, where b is the length of the base and his the height. Rearrange the formula t
NeX [460]

Answer:

h = 2A/b

Step-by-step explanation:

Area of a triangle, A = 1/2bh

Where,

b = base of the triangle

h = height of the triangle

Rearrange the formula to isolate h

A = 1/2bh

Multiply both sides by 2

2 * A = 2 * 1/2bh

2A = bh

Divide both sides by b

2A / b = bh / b

2A / b = h

Therefore,

h = 2A/b

Elimination Method: 6x - 4y = -24 and 4x + 5y = -2
nirvana33 [79]

Answer:

(-2;-6)

Step-by-step explanation:

First of all, let's rewrite the first one after dividing both sides by 2.

\left \{ {{3x-2y=-12\atop {4x+5y=-2}} \right.

Now, let's pick one you want to eliminate.

<u>Eliminating x:</u> Let's multiply the first one by 4, the second by 3, and subtract one from the other. Rest is simply solving an equation in one variable

4I-3II : 12x-8y-12x+15y = -48 - (-6)\\7y = -42 \rightarrow y= -6

<u>Eliminating y:</u> Let's multiply the first by 5, the second by 2, and add them together. Rest is simply solving an equation in one variable

5I+2II: 15x -10y +8x +10y = -60 +4\\23x = -56 \rightarrow x=-2

Oliga [24]
I don't have my calculator handy just now. But just looking at that problem, why don't you try +20 and -45 and see if they do the job.

Tao uses elimination to solve the following system of linear equations. -2x+4y=162x+2y=8Which ordered pair is a solution to the
Alex_Xolod [135]

The correct answer is the first option.


If you want to use elimination, you can sum the two equations for example, so that the x's simplify:


(-2x+4y)+(2x+2y) = 16+8


6y = 24


y = 4


Plug this value for y in one of the equations to derive the value of x:


2x+2y=8 \implies 2x + 8 = 8 \implies x = 0


So, the solution is (x,y) = (0,4)
