If 7/12x-1/3=1/2+3/8 what is the value of x

telo118 [61]

$\dfrac{7}{12}x-\dfrac{1}{3}=\dfrac{1}{2}+\dfrac{3}{8}\\\\LCM(12,\ 3,\ 2,\ 8)=24\\\\\text{multiply both sides by 24}\\\\24\cdot\dfrac{7}{12}x-12\cdot\dfrac{1}{3}=12\cdot\dfrac{1}{2}+24\cdot\dfrac{3}{8}\\\\2\cdot7x-8=12+3\cdot3\\\\14x-8=12+9\\\\14x-8=21\qquad|\text{add 8 to both sides}\\\\14x=29\qquad|\text{divide both sides by 14}\\\\x=\dfrac{29}{14}$

Differentiating a Logarithmic Function in Exercise, find the derivative of the function. See Examples 1, 2, 3, and 4.

bekas [8.4K]

Answer:

$\frac{dy}{dx}=-\frac{3}{2(1-x)}$

Step-by-step explanation:

We are given that a function

$y=ln(1-x)^{\frac{3}{2}}$

We have to find the derivative of the function

$y=\frac{3}{2}ln(1-x)$

By using $lna^b=blna$

Differentiate w.r.t x

$\frac{dy}{dx}=\frac{3}{2}\times \frac{1}{1-x}\times (-1)$

By using formula

$\frac{d(lnx)}{dx}=\frac{1}{x}$

$\frac{dy}{dx}=-\frac{3}{2(1-x)}$

Hence,the derivative of function

$\frac{dy}{dx}=-\frac{3}{2(1-x)}$

Solve the quadratic equation:

Umnica [9.8K]

Answer:

Step-by-step explanation:

$x^2+7x+10=0\qquad\implies\quad a=1\,,\ b=7\,,\ c=10\\\\\\x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-7\pm\sqrt{7^2-4(1)(10)}}{2(1)}=\dfrac{-7\pm\sqrt{49-40}}{2}=\dfrac{-7\pm\sqrt9}{2}\\\\ x_1=\dfrac{-7+3}2=\dfrac{-4}2=-2\,,\qquad x_1=\dfrac{-7-3}2=\dfrac{-10}2=-5$
