Δlʹmʹnʹ is a dilation of δlmn with the origin as the center of dilation. the coordinates of the vertex of ∠lmn are (40, 55). if the scale factor is , what are the coordinates of the vertex of ∠lʹmʹnʹ? ( , )

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
