Answer:
x = 24
Step-by-step explanation:
1.) put the equations together and equal them to 180
2x + 4 + 6x - 16 = 180
2.) combine like terms
8x - 12 = 180
3.) divide both sides by 8
8x = 192
4.) simplify
x = 24
I think it would be 100/20
The correct answer is A) {(1, 3), (4, 2), (5, 2), (4, 1} and <span>D) {(1, 2), (4, 3), (1, 5), (5, 6)}.</span>
Answer:
A)
But really there is no effect since cos(-x)=cos(x).
Step-by-step explanation:
Cosine is an even function.
Even functions are symmetric about the y-axis.
So really for cosine; cos(-x) has no change to cos(x) since they are equal.
But if you keep in mind that cosine is symmetric about the y-axis, then it has been reflected over the y-axis; this is the vertical axis.
