x = 3
Multiplicative identity, which states that anything multiplied by 1 is itself.
Answer:
y - 5= 5(x-x)
Step-by-step explanation:
Point slope form is y - y(1) = m( x- x (1))
So just put in the information the question gave you
y - 5= 5(x-x)
If you have x, just put the x in the x(1) spot and you're set!
Hope this helped! :)
Answer:
Step-by-step explanation:
You could do this one of 2 ways. First is to look at the graph and locate x = 0. That is the y-axis. ON the y axis, the cosine curve is at a y value of 1. Second way is to go to your calculator and, in degree mode, hit cos(0) and you'll see that it is 1.
