z= 2y-4x ok i hope this helps.
≥ the graph would be going to your right
≤ the graph would be going to your left
Both cases assume x is on the left side of the inequality.
If the circle is open < or > will be used.
If the circle is shaded in then use ≤ or ≥
If the circle is open, then x<2 would indicate that the ray is going left (which it is) and 2 is not included.
Answer: x < 2
Answer:
sin 5x cos x - cos 5x sin x = sin(4x)
Step-by-step explanation:
Given that the trigonometric expression,
sin 5x cos x - cos 5x sin x
Here we use the "sum and difference formulas"
Sum and Difference Formulas
sin(A+B)=sin A cos B + cos A sin B
sin(A-B)=sin A cos B - cos A sin B
cos(A+B)=cos A cos B - sin A sin B
cos(A-B)=cos A cos B + sin A sin B
So,
sin 5x cos x - cos 5x sin x = sin (5x - x)
sin 5x cos x - cos 5x sin x = sin(4x)
That's the final answer.
3n2 -8n2 -5n-3n+6-2 = -5n2-8n+4
