Answer:

Step-by-step explanation:

convert mixed fraction into improper fraction.

calculate the sum of the fraction:

Answer:
option 2
Step-by-step explanation:
consider the coordinates A (- 3, 4 ) and A' (- 1,
)
since the dilatation is centred at the origin, then corresponding coordinates are multiples/ divisors of each other, then image to original gives scale factor.
scale factor =
=
=
and
= 
similarly B (1, - 2 ) and B' (
, -
)
=
and
= 
A vertical shift adds/subtracts a constant to/from every y-coordinate while leaving the x-coordinate unchanged. A horizontal shift adds/subtracts a constant to/from every x-coordinate while leaving the y-coordinate unchanged. Vertical and horizontal shifts can be combined into one expression.
Shifting up or to the right means add
Shifting down or to the left means subtract
the 3rd option is the correct one
Rounded to the nearest cent, the answer is 1.19
Just add them all up that’s it and you will get 20
