The answer to the question is (2,-2) d
When grades are expressed as a quantity of 1, such as two feet per second or 5 miles per hour, they are called unit rates.
Answer:
Answer:
A. 2 sinx cosx - 1 + 2 sin^2 x.
Step-by-step explanation:
sin2x = 2 sinx cosx
cos2x = cos^2x - sin^2x
So sin2x - cos2x = 2 sinx cosx - ( cos^2x - sin^2x)
But cos^2 x = 1 - sin^2 x, so we have:
2 sinx cosx - (1 - sin^2 x - sin^2x)
= 2 sinx cosx - 1 + 2 sin^2 x.
Answer:
B
Step-by-step explanation:
y = mx + b
The slope is m.
If it was anything other than 0, the line would have an x in it. The line does not have an x associated with it.
The equation of the line is y = 1
The slope must be 0.
