How do you find the ratio of x and y coordinates

Firdavs [7]

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.

Answer: 0.8

Step-by-step explanation:

The formula to find area of a parallelogram is A = bh. This means that area = base x height. You can manipulate this formula to what height equals instead of the area. To do that, you can divide b on both sides. This would make the equation h = A/b.

Now that you know how to find what height equals, first find the base of the parallelogram. To find b, multiply 6 x 5. 6 x 5 = 30. This means that your base is 30.

Take the information given to you in the problem about the area. The area is given to you. We know that the area is 24 squared units. Remember what the equation to find height is. It's h = A/b. Substitute the variables for your numbers. h = 24/30.

24/30 = 0.8.

This means that your height is 0.8. This would be 8/10 in fraction form, but you can simplify it further to 4/5.

Hope it helps. Good luck!

50 POINTS! Reflect quadrilateral PQRS about the y-axis. Then translate the resulting quadrilateral 2 units down.

timama [110]

Answer:

D.) P’(12, 6), Q’(8, 7), R’(4, 4), and S’(7, 1)

Step-by-step explanation:

Reflection over the y-axis changes the sign of the x-coordinate:

(x, y) ⇒ (-x, y) . . . . . reflection over the y-axis

Translation 2 units down, subtracts 2 from the y-coordinate:

(x, y) ⇒ (x, y -2) . . . . . translation 2 units down

The combined transformation is ...

(x, y) ⇒ (-x, y -2) . . . . . reflection over y-axis and translation 2 down

For point P, the image coordinates are ...

P(-12, 8) ⇒ P'(-(-12), 8 -2) = P'(12, 6) . . . . matches choice D
