Answer:
True, they form a proportion because their cross-multiplication products are equal.
Step-by-step explanation:
True or False?
If they are a proportion, the products you get from cross-multiplying are the same.
Multiply the left numerator by right denominator:
49 X 12 = 588
Multiply the left denominator by right numerator:
21 X 28 = 588
588 = 588
Therefore it is true, 49/21 and 28/12 form a proportion.

Answer:
The parent function f(x) is equal to
The translations is 3 units to the left and 5 units down
Step-by-step explanation:
we have
The vertex of the function h(x) is the point (-3,-5)
we know that the parent function f(x) is equal to
The vertex of the function f(x) is the point (0,0)
so
The rule of the transformation of f(x) to h(x) is equal to
(x,y) -----> (x-3,y-5)
That means ----> The translations is 3 units to the left and 5 units down
