Is the inverse of an ordered pair on a graph is it’s reflection across the line y=x , sometimes, always, or never true?

Always

Step-by-step explanation:

Finding the inverse of an ordered pair is simply swapping the position of x and y coordinates

if a point is (2,3), then the inverse is (3,2)

In general a point (x,y) will have its inverse as (y,x)

So now a point lets see a point  (x,y) reflected on line  on line y=x  , the resulting image of the point will be (y,x)

For example point (1,2) reflected on y=x will have image at (2,1)

This means that inverse of an ordered pair on a graph is its reflection across the line y=x always

answer: 59

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
