Answer:
<h2>2x + 3</h2>
Step-by-step explanation:
f(2x) means that we have to substitute x with 2x
So, the answer is
2x + 3
The rule of the transformation is
(x,y)->(-y,x)
which corresponds to a 90 counterclockwise rotation about the origin,
which in turn corresponds to a 270 clockwise rotation about the origin.
Note that all rotations preserve lengths and angles, hence the image and preimage are congruent.

Find x
(a)
x is calculated using tangent formula
Make x the subject
--- approximated
(b):
x is calculated using cosine formula
Make x the subject
(c):
x is calculated using sine formula
Make x the subject
--- approximated
You can determine if the answer is positive or negative because the even numbers are positive and the odd numbers are negative
rate of blowing balloons of Alexa = 15/20 = 0.75
rate of blowing balloons of Sara = 18/25 = 0.72
rate of blowing balloons of Shirley= 16/21 = 0.76
rate of blowing balloons of Sam = 12/23 = 0.52
from above calculation we concluded Shirley can blow balloons at the fastest rate!
