Consider the differential equation dy /dx =1-y/e^xwith a particular solution y = f(x) having an initial condition y(0) = 2. Use the equation of the line
tangent to the graph of f at the point (0, 2) in order to approximate the value
of f(-0.2).

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

you divide them and then you get the answer i took this class this year
