4x-6+x+3<br><br> what is the value of this expression if x=8

vlabodo [156]

Answer:

$\frac{dy}{dx} = \frac{ \cos(x + y)}{[1 - \cos(x + y)] }$

Step-by-step explanation:

Let y = sin(x+y)

Differentiating with respect to x on both sides.

$\frac{dy}{dx} = \frac{d}{dx} \sin(x + y) \\ \\ \frac{dy}{dx} = \cos(x + y)\frac{d}{dx} (x + y) \\ \\ \frac{dy}{dx} = \cos(x + y)(1 + \frac{dy}{dx}) \\ \\ \frac{dy}{dx} = \cos(x + y) +\cos(x + y) \frac{dy}{dx} \\ \\ \frac{dy}{dx} - \cos(x + y) \frac{dy}{dx} = \cos(x + y) \\ \\ \frac{dy}{dx} [1 - \cos(x + y)] = \cos(x + y) \\ \\ \purple {\bold {\frac{dy}{dx} = \frac{ \cos(x + y)}{[1 - \cos(x + y)] }}}$

It's 9 4/5 miles from Justin's house to the art museum the distance to the history museum is 9/10 this far

Leno4ka [110]

The history museum is less that 9 4/5 miles. 9/10 means that the 9 3/4 mile is broken up into 10 equal parts and the distance to the museum is only 9 of those parts. 9 3/4 (9.8) divided by 10 equals 98/100 (.98)
98/100 x 9 = 882/100 or 8.82

Justin's house is 8.82 miles from the museum.
