If your question is "what time was it before the elapsed time", then the answer will be 9:38. All you have to do is to deduct the time by 30 minutes based on your clock, and you will be able to get the answer right away. Also, if you add 9:38 by 30 minutes, you will get 10:08 as well.
Cos x = -12/13
sin x = -sqrt(13^2 - 12^2) / 13 = -5/13
tan x = 5/12
tan x/2 = (1 - cos x) / sin x = 1 - (-12/13) / -5/13 = 25/13 * -13/5 = -5
2sin^2 x/2 = 1 - cos x = 1 - (-12/13) = 25/13
sin^2 x/2 = 25/13 / 2 = 25/26
sin x/2 = 5/√26
sin x/2 / cos x/2 = tan x/2
cos x/2 = sin x/2 / tan x/2 = 5/√26 / -5 = -1/√26
sin x/2 = 5/√26
cos x/2 = -1/√26
tan x/2 = -5
Answer:
No solutions.
Step-by-step explanation:
Both equations have the same slope, but are separated by virtue of their different values of b, the y-intercept. The same slope means they are parallel lines. Since the y-intercept is different, they do not overlap.
As they say, "Parallel line have a lot in common. Too bad they'll never meet."

Answer:
y= 3x -5
Step-by-step explanation:
since when x is 0, and y is -5, you know that the y intercept is -5.
look at the table
1x -5 = -2
x= 3
Boom.
LONG LIVE KOREA!
Step-by-step explanation:
Erase the dot points you already have. We are supposed to substitute those values in the right side of problem 1 into the function as x.
For example if x=-4

If x=-2

If x=0



So our point should be
-4,9
-2,7
0,5
-2,3
-4,1.
The range is all possible y values in a function. Since this is discrete and we are given the domain, our range will just be the y value of the points you graphed.
(9,7,5,3,1)
