Answer:
Step-by-step explanation:
sin(x) + tan(x)=sin(X) + sin(x)/cos(x)
=sinx(1+1/cosx)
=sinx(1+secx)
=1+secx/cosecx. (Since sinx=1/cosecx)
Hence LHS=RHS proved
First, you would subtract 4.25 from 6.25 and that would be equal to 2.
Then, you would take 2.25z and subtract it from 3.5z and it would equal 1.25z.
Next, you would separate the z by dividing 1.25 on both sides. Z=1.6

Answer:
- NOT a function
- domain: [-2, 2]
- range: [-4, 4]
Step-by-step explanation:
A vertical line intersects the graph twice, so the relation is not a function. It is only allowed to intersect once if the relation is a function.
The domain is the horizontal extent, which is from -2 to +2.
The range is the vertical extent, which is -4 to +4.
