Samaria has 6 more than three times as many pieces of candy as sydney. samaria has 36 pieces of candy. how many does sydney have

lesya [120]

For this case we have:

x: Number of candies that Sydney has

The equation to find the amount of Sydney sweets is given by:

$3x + 6 = 36$

We want to clear x:

$3x = 36-63x = 30$

$x = \frac{30}{3}$

$x = 10$

So, Sydney has 10 candies

Answer:

Sydney has 10 candies

If f(x)=ln(sin(2x)), f''(π/4) is equal to

Licemer1 [7]

Use the chain rule to compute the second derivative:

$f(x)=\ln(\sin(2x))$

The first derivative is

$f'(x)=(\ln(\sin(2x)))'=\dfrac{(\sin(2x))'}{\sin(2x)}=\dfrac{\cos(2x)(2x)'}{\sin(2x)}=\dfrac{2\cos(2x)}{\sin(2x)}$

$f'(x)=2\cot(2x)$

Then the second derivative is

$f''(x)=(2\cot(2x))'=-2\csc^2(2x)(2x)'$

$f''(x)=-4\csc^2(2x)$

Then plug in π/4 for <em>x</em> :

$f''\left(\dfrac\pi4\right)=-4\csc^2\left(\dfrac{2\pi}4\right)=-4$

PLEASE HELP MEE!! IVE BEEN DOING THIS ASSIGNMENT FOR OVER 2 HOURS NOW, PLS HELP.. :(

Answer:

x = -3, y = 5

Step-by-step explanation:

first, take the 3x + 17 = y and put it in place for the y in the second equation.

-3x=4x+17+4

then, solve the equation.

-3x=4x+21

-3x-4x=4x-4x+21

-7x=21

-7/-7x=21/-7

x = -3

substitute in other equation

4(-3) + 17 = y

-12 + 17 = y

y = 5

answers are x = -3 and y = 5
