5 0

Answer:

(7, -3)

Step-by-step explanation:

9x - 3y = 54

9x +1 ly = 12

Subtract both expresion

-3y - 11y = 54 - 12

-14y = 42

y = 42/-14

y = -3

Substitute y = -3 into 1;

From 1, 9x - 3y = 54

9x - 3(-3) = 54

9x - 9 = 54

9x = 54 + 9

9x = 63

x = 63/9

x = 7

Hence the solution to the system of equation is (7, -3)

What is the d/dx tan^3x
Bad White [126]

= 3(tanx)^{2} \cdot sec^{2}x

\therefore \frac{d}{dx}(tan^{3}x) = 3tan^{2}x \cdot sec^{2}x
