Left side:
1-sin²(x) = cos²(x)
1-sin²(x) / cos(x) = cos²(x) / cos(x) = <em>cos(x)</em>
Right side:
sin(2x) = 2 sin(x) cos(x)
sin(2x) / 2 sin(x) = 2 sin(x) cos(x) / 2 sin(x) = <em>cos x </em>
Answer: (0,5) is the answer
Step-by-step explanation:
y=mx+b (always remember this when dealing with problems like this* (m is the slope, and b is the y intercept)
in your equations, the m is 1 (since there is no value visible, it is assumed to be a 1)This means each time you move right one x value, you move up one y value. The b in your equation is a 5, so the coordinate is simply (0,5)
(-7,4),(-8,3)(-7,7),(-20,8),(5,9),(3,1),(2,6) state whether each set of ordered pairs represents a function

Answer:
This relation is NOT a function.
Step-by-step explanation:
Just check the x's. If you have a repeat (the first x is -7, but so is the x on the third point)
If the x's repeat it has to be exactly the same point (same y both times)
If the x's repeat and have different y's, then the relation is NOT a function.
Add 6 left and right and get: g-6+6 > -1+6 =>
g>5
