Answer:
A
Step-by-step explanation:
This isn't an equation because there is no = sign so we can eliminate B and C. Since this has variables in it it's algebraic so the answer is A.
Step-by-step explanation:
csc x / (cot x + tan x)
Write in terms of sine and cosine.
(1 / sin x) / [(cos x / sin x) + (sin x / cos x)]
Multiply top and bottom by sin x.
1 / [cos x + (sin²x / cos x)]
Multiply top and bottom by cos x.
cos x / (cos²x + sin²x)
Use Pythagorean identity.
cos x / 1
cos x
Answer: straight line across on the y axis on -2/3
Step-by-step explanation:
Answer:
The solution to the graph are x = -2 and x = 2
Step-by-step explanation:
Here, we want to get the solution to the graph
As we can see, the graph is parabolic; which is a property of a quadratic polynomial
The solution refers to the value at which the graph plot crosses the x-axis
In other words, the solutions to the graph are represented by the point at which we have the graph crossing over the x-axis
We can see this happen at two points
These are the points x = -2 and x = 2
