Let Q be the set of rational numbers, so any element in Q can be written as the form of x y , here x is an integer, and y is a nonzero integer. Let Z be the set of integers. Define the mapping f : Q → Z by f( x y ) = x − y for any x y ∈ Q. Here x is any integer and y is any nonzero integer

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
