]Choose the equation below that represents the line passing through the point (-2, -3) with a slope of -6. . . y + 3 = -6(x + 2)
pshichka [43]
Y - y1 = m(x - x1)
slope(m) = -6
(-2,-3)...x1 = -2 and y1 = -3
now sub and pay close attention to ur signs
y - (-3) = -6(x - (-2)....we're not done yet...
y + 3 = -6(x + 2) <===

Write an equation of the line that passes through (2,-3) and is perpendicular to the line y=-2x-3
Alina [70]

Answer:

y = 1/2 x - 4

Step-by-step explanation:

slope of perpendicular line is 1/2

y +3 = 1/2 (x -2)

y + 3 = 1/2x - 1

y = 1/2x - 4

A tank initially contains 40 ounces of salt mixed in 100 gallons of water. a solution containing 4 oz of salt per gallon is then
stellarik [79]
Let A(t) be the amount of salt in the tank at time t. We're given that A(0)=40. The rate at which this amount changes is given by

A'(t)=\dfrac{5\text{ gal}}{1\text{ min}}\cdot\dfrac{4\text{ oz}}{1\text{ gal}}-\dfrac{5\text{ gal}}{1\text{ min}}\cdot\dfrac{A(t)\text{ oz}}{100+(5-5)t\text{ gal}}

A'(t)+\dfrac{A(t)}{20}=20

e^{t/20}A'(t)+e^{t/20}\dfrac{A(t)}{20}=20e^{t/20}

\bigg(e^{t/20}A(t)\bigg)'=20e^{t/20}

e^{t/20}A(t)=400e^{t/20}+C

A(t)=400+Ce^{-t/20}

Since A(0)=40, we get

40=400+C\implies C=-360

so that the amount of salt at time t is

A(t)=400-360e^{-t/20}

After 20 minutes, the tank contains

A(20)=400-360e^{-20/20}\approx267.56\text{ oz}
