Step-by-step explanation:

Step 1: Define

Identify

f(x) = 2x - 6

g(x) = 3x + 9

(f + g)(x) is f(x) + g(x)

Step 2: Find

Substitute in function values: (f + g)(x) = 2x - 6 + 3x + 9
Combine like terms: (f + g)(x) = 5x + 3

Solve the inequality. 5 - 4x > 3x - 9

Olegator [25]

Answer:

2 >x

Step-by-step explanation:

5 - 4x > 3x - 9

Add 4x to each side

5 - 4x+4x > 3x+4x - 9

5 > 7x-9

Add 9 to each side

5+9> 7x-9+9

14>7x

Divide each side by 7

14/7 >7x/7

2 >x

Answer: -ln |cos x| - ln |sin x| + C

Step-by-step explanation:

$.\quad \int\dfrac{sin^2x-cos^2x}{sin\ x\ cos\ x}dx\\\\\\=\int \dfrac{sin^2x}{sin\ x\ cos\ x}dx-\int \dfrac{cos^2x}{sin\ x\ cos\ x}dx\\\\\\=\int \dfrac{sin\ x}{cos\ x}dx-\int \dfrac{cos\ x}{sin\ x}dx\\\\\\=\int tan\ x\ dx - \int cot\ x\ dx\\\\=-ln |cos\ x|-ln|sin\ x| + C$
