Solve each equation:
serious [3.7K]

Step-by-step explanation:

1) -7 (divide -28 by 4 to isolate x)

2) -8 (two negatives = a positive, so it's x + 6 = -2, then subtract 6 from both sides)

3) 5 (subtract 4 from both sides, and multiply each side by -1)

4) 2 (subtract 7 from both sides, then divide by -3)

5) -3 (add 11 to both sides then divide by 25)

Differentiate y = 8x/ 3 − tan(x)
vagabundo [1.1K]

Answer:

\frac{dy}{dx}=\frac{8(xsec^2(x)-tan(x)+3)}{(3-tan(x))^2}

Step-by-step explanation:

y=\frac{8x}{3-tan(x)}\\ \\\frac{dy}{dx}=\frac{(3-tan(x))(\frac{d}{dx}8x)-(\frac{d}{dx}(3-tan(x)))(8x)}{(3-tan(x))^2}\\ \\ \frac{dy}{dx}=\frac{(3-tan(x))(8)-(-sec^2(x))(8x)}{(3-tan(x))^2}\\ \\ \frac{dy}{dx}=\frac{24-8tan(x)+8xsec^2(x)}{(3-tan(x))^2}\\ \\ \frac{dy}{dx}=\frac{8xsec^2(x)-8tan(x)+24}{(3-tan(x))^2}\\\\ \frac{dy}{dx}=\frac{8(xsec^2(x)-tan(x)+3)}{(3-tan(x))^2}

If the circulation for newspaper 1 is 382 thousand more than the circulation for newspaper 2 and their combined is 2502 thousand
goldenfox [79]

If the circulation for newspaper 1 is 382 thousand more than the circulation for newspaper 2 and their combined is 2502 thousand find the circulation for each paper

Answer: Let x be the circulation for newspaper 2.

Then the circulation for newspaper 1 is x +382 thousand

We are given the combined circulation of newspaper 1 and newspaper 2 is 2502 thousand

\therefore x+(x+382)=2502

2x+382=2502

2x=2502-382

2x=2120

x=\frac{2120}{2} =1060

Therefore, the circulation of newspaper 2 is 1060 thousand and circulation of newspaper 1 is 1060 + 382 = 1442 thousand
