Answer:
3x-6y
Step-by-step explanation:
3/4(4x-8y)
3/4×(4x-8y)
3/4×4(x-2y)
3×1(x-2y)
3x-6y
Do you have the answer choices?
We know that
Limacons are in the form
r=a(+-)b*sin (theta) or r=a(+-)b*cos (theta)
in this problem
r=a(+-)b*sin (theta)
so
is symmetric to y axis
a=1/2
b=1/2
a/b=1---------> Cardioid (hearth shaped)
see the attached figure
the answer is the option
<span>
A. Cardioid </span>
