How would I reduce this to lowest terms?

Andrew [12]

Since "a" is on the top and the bottom, you can simplify that

$\frac{a^2b^2}{ac}$

$\frac{ab^2}{c}$

Find the general solution for the differential equation (dy)/(dx) + 3y = 18<br> Y=

harkovskaia [24]

Answer:

$y=-e^{-3x-c_1}+6$

Step-by-step explanation:

$\frac{dy}{dx}+3y=18\\\\\mathrm{Substitute\quad }\frac{dy}{dx}\mathrm{\:with\:}y'\:\\\\y'\:+3y=18\\\\Rewrite\\\\\frac{1}{6-y}y'\:=3\\\\Solve \::\frac{1}{6-y}y'\:=3\\\\-In(6-y)=3x+c_1\\\\Isolate\:y\\\\\\y=-e^{-3x-c_1}+6$

write the equation of a line that is perpendicular to the line y=-3/7-15 and that passes through the point (9,2)

SashulF [63]

Answer:

Step-by-step explanation:

First substitue the coordinates to the equation so

x=9, y=2

you would get

2=-3/7(9) + b

we put b because we are trying to find the new slope

multiply the two numbers above

2=-3/6/7 + b

subtract the whole number from both sides

b= 5/6/7

in equation would be

y= -3/7 + 5/6/7

Let me know if there is an error.
