Answer:
-15/2 =x
Step-by-step explanation:
12(x+5)=4x
Distribute
12x +60 = 4x
Subtract 12x from each side
12x-12x +60 = 4x-12x
60 = -8x
Divide each side by -8
60/-8 = -8x/-8
15/-2 = x
-15/2 =x
Step-by-step explanation:
1. All the trigonometric values can be found using the unit circle. See attached table.
2. Graph:

3. All trig functions are periodic functions. The period of secant and cosecant is 2π. The period of cotangent is π.
4. Using the table from step 1 and the graph from step 2, secant has a domain of x ≠ pi/2, 3pi/2 and a range of x ≤ -1, x ≥ 1. Cotangent has a domain of x ≠ 0, pi, 2pi and a range of -∞ < x < ∞.
5. Graph:

Cosecant has the same graph as secant shifted π/2 to the right. So they have different domains, but the same range.
