Answer:
if your simplifying it is 3x^2 + 9x
Step-by-step explanation:
(3y + 7) + (5y-7)= 8y
(4y - 5)- 8y= -4y-5
This ODE is separable, so you can write

Integrating both sides gives

and given the initial condition

, you have

so that the solution is
Answer:
cos 60° isn't equivalent
Step-by-step explanation:
cos 60°=1/2
Answer:
Slope-intercept form is
y = mx + b
We want to get the y by itself on one side of the equation.
0 = 18x + 6y – 2
First let's subtract 6y from both sides.
-6y = 18x – 2
Next let's divide both sides by -6.
y = (18 / -6)x - (2 / -6)
y = -3x + 1/3
...The last instructions are kind of confusing to me, but I think that is the answer you're after. :)
