The rule for dilation (scale factor k) about the origin is given by:
(x,y)->(kx,ky)
The scale factor k can be obtained from any one of the ratios:
Let x = adult tickets
Let y = children's tickets
x + y = 800
8x + 4y = 4,400
From the first eq, x = 800 - y, plug this in to the second eq
8(800-y) + 4y = 4,400
6400 - 8y + 4y = 4,400
2000 = 4y
500 = y
x = 800 - 500
x = 300
300 adult tickets were sold.
Answer:
B
Step-by-step explanation:
cause it is
Cross multiplying:-
cot^2 x = (csc x+ 1)(csc x + 1)
also cot^2 x = csc^2 x - 1 = (csc x + 1)(csc x - 1) (Known Identitiy)
so the equation is not an identity
is the difference between 
Step-by-step explanation:
Given equations,

Difference of the polynomial is written as

Open the brackets and multiply with -1 the whole expression
becomes


This is the difference of given two polynomials is
