Answer:

Step-by-step explanation:
Given:
Number of feathers = 
Number of caps = 
Number of feathers in each cap = 3
Now, solving by setting up a proportion.
1 cap has 3 feathers. 'c' caps has 'f' feathers.
This gives,

Solving by cross multiplication, we get:

Therefore, the equation representing the number of feathers 'f' Erica needs to make 'c' caps is given as:


Find the LCD 4 and 6 :
factor each denominator into its primes:
4 = 2²
6 = 2 * 3
Find the least common denominator 2² * 3 = 12

X=0 is actually the y axis, so the y coordinate of the reflection doesn't change, while the x coordinate changes from a negative to a positive or from a positive to a negative.
the new confidante of D is (1,-1)
The answer to that would be -1t
