It looks like a rotation of 270 degrees counter-clockwise and a dilation (enlargement) of 2 times.
Hope this helps answer your question!

Answer:
18
Step-by-step explanation:
Solve the first for a, then substitute into the second.
a = 27/(5b^2)
Then ...
(27/(5b^2))^2·b = 135
27^2/(5^2·135) = b^3 = 27/125
b = ∛(27/125) = 3/5
a = 27/(5(3/5)^2) = 15
__
The expression of interest is ...
a +5b = 15 + 5(3/5) = 15 +3
a +5b = 18
Step-by-step explanation:
A relationahip is proportional if both variables can be both 0.
y = 0.5x
(0) = 0.5(0)
Since the equality is true, it is proportional.
To graph the function, plot (0, 0) and (10, 5) on the graph and draw a line through the points.
Hope i understand it right
9y^2 -12y^4 = 3y^2 *(3 - 4y^2)
