Use the addition and subtraction theorem:
sin (A + B) = sin A + cos B
sin (A - B) = sin A - cos B
From there it's just a matter of simplification.
sin A cos B = 1/2 [ sin (A + B) + sin (A - B) ]
sin A cos B = 1/2 [ sin A cos B + cos A sin B + sin (A - B) ]
sin A cos B = 1/2 [ sin A cos B + cos A sin B + sin A cos B - cos A sin B ]
sin A cos B = 1/2 [ 2 sin A cos B ]
sin A cos B = sin A cos B
First find the slope.
We know these two points are in the line: (0,8) and (6,5)

The slope is -1/2. The y-intercept can be found when x = 0. And we know that the point (0,8) is on the line and x = 0, therefore the y-intercept is 8.
Plugging this into the slope-intercept form which is
y = mx + b, where m is the slope and b is the y-intercept, we get:
y = (-1/2)x + 8
Answer:
o.42
Step-by-step explanation:
Answer: circle 2 and 5
Step-by-step explanation:
The problem is asking which number can 428 by divided by evenly.
Step 1: 428 divided by 2 is 214 Since it was evenly divided, you circle 2. It is the same for 4.
Step2: Keeping dividing each of the numbers to see if 428 can by divided by the number. If the answer comes out as a decimal number than don’t circle.
G= -36
