What is this problem in standard form? y-5=3/2(x+6)

givi [52]

Answer:

$\displaystyle \boxed{3x - 2y = -28}$

Step-by-step explanation:

y - 5 = 3⁄2(x + 6)

y - 5 = 3⁄2x + 9

+ 5 + 5

__________

y = 3⁄2x + 14

- 3⁄2x - 3⁄2x

________

−3⁄2x + y = 14 [We do not want mixed numbers\fractions in our standard equation, so multiply by the denominator to get rid of it.]

−2[−3⁄2x + y = 14]

$\displaystyle 3x - 2y = -28$

An oil storage tank ruptures at time t = 0 and oil leaks from the tank at a rate of

$\displaystyle\int_0^{60}r(t)\,\mathrm dt=\int_0^{60}80e^{-0.01t}\,\mathrm dt$

Let $u=-0.01t$ so that $-100\mathrm du=\mathrm dt$ . Then the integral becomes

$\displaystyle-8000\int_0^{-0.6}e^u\,\mathrm du=8000\int_{-0.6}^0e^u\,\mathrm du=8000(e^0-e^{-0.6})\approx3610\text{ L}$
