Which algebraic representation shows an enlargement?
(x, y) → (12x, 12y)
(x, y) → (3x, y)
(x, y) → (x+3, y+3)
(x, y) → (3x, 3y)

(x, y) → (12x, 12y)

(x, y) → (3x, 3y)

Step-by-step explanation:

When we enlarge by a scale factor of k, about the origin, the rule is

An enlargement could be a magnification or a reduction.

When

the enlargement is a reduction.

When

the enlargement is a magnification.

Therefore we have two correct answers.

(x, y) → (12x, 12y)

(x, y) → (3x, 3y)

answer: for each 3 girls there is 2 boys . 3: 2

hope this ! (:   mark me as brainliest if you can

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
