Which statement represents the simplified form of the given equation and correctly describes the solution?

exis [7]

Hence the correct answer is:

D. 6=6; infinite real solutions

Further explanation:

In order to find the simplified form of the equation we have to isolate the variable on one side of the equation.

Given equation is:

$9x+6=3(3x+2)$

Taking 3 common on left hand side

$9x+6=9x+6\\9x-9x+6=6\\6=6$

The equation has infinite real solutions.

Hence the correct answer is:

D. 6=6; infinite real solutions

Keywords: Solution of equation, infinite solutions

Use fundamental theorem of calculus to find derivative of the function LOOK AT PHOTO

kykrilka [37]

Let c > 0. Then split the integral at t = c to write

$f(x) = \displaystyle \int_{\ln(x)}^{\frac1x} (t + \sin(t)) \, dt = \int_c^{\frac1x} (t + \sin(t)) \, dt - \int_c^{\ln(x)} (t + \sin(t)) \, dt$

By the FTC, the derivative is

$\displaystyle \frac{df}{dx} = \left(\frac1x + \sin\left(\frac1x\right)\right) \frac{d}{dx}\left[\frac1x\right] - (\ln(x) + \sin(\ln(x))) \frac{d}{dx}\left[\ln(x)\right] \\\\ = -\frac1{x^2} \left(\frac1x + \sin\left(\frac1x\right)\right) - \frac1x (\ln(x) + \sin(\ln(x))) \\\\ = -\frac1{x^3} - \frac{\sin\left(\frac1x\right)}{x^2} - \frac{\ln(x)}x - \frac{\sin(\ln(x))}x \\\\ = -\frac{1 + x\sin\left(\frac1x\right) + x^2\ln(x) + x^2 \sin(\ln(x))}{x^3}$
