Which rule describes the translation below? (x, y) →(x-5.y-3)
(x, y) →(X+5.y+3) (x, y) → (x-3.y-5)
(x, y) → (x+3.y+5)

first option

Step-by-step explanation:

Consider the coordinates of points T andT'

T (1, 1 ) and T' (- 4, - 2 )

To go from 1 to - 4 in the x- direction means subtracting 5

To go from 1 to - - 2 in the y- direction means subtracting 3

Then translation rule is (x, y ) → (x - 5, y - 3 )

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

6 purchases

if you are asking how many of each then:

18 social media ads

6 newspaper ads

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
