Find all real or imaginary solutions to the equation. x-1 2x - 3 ---- = ------- x+2 x+4

Graph the equation: y=-3|x+5|+3

The stabilization ratio (births/deaths) for South and Central America can be modeled by the formula y = -0.0012x^2 + 0.074x + 2.69 where y is the number of births divided by the number of deaths in the year 1950 + x a) use a graph to estimate the year in which the stabilization ratio was at its maximum. b) use the formula to

Find all real or imaginary solutions to each equation. Use any method to solve. x^2 = -121 keywords: complex

A colony of 1000 bacteria is introduced to a growth-inhibiting environment and grows according to the formula n = 1000 + 50t + t^2 How many bacteria are present after 3 hours?

Solve for t. Where t is a real number. Divide with commas, if there is more than one solution. principle square root t + 19=4

Evaluate. b=-2 and c=3 -8 b+c

I have been tasked with solving y'' - 3y^2 =0 using the technique used substituting v for y', therefore substituting v dv/dy for y''. (Equation with "x" missing) I broke it down as follows Y'' -3y^2 =0 Y'' =3y^2 Substituting I get v dv/dy = 3y^2 Separating variables, I get v dv =3y^2dy Integrating I get 1/2v^2 +c = y^3 +c

Anne is pulling on a 60 foot rope attached to the top of a 48 foot tree while Walter is cutting the tree at its base. How far from the base of the tree is Anne standing?

Perform the operation. Write answer in the form a + bi 6 + principle square root -18 --------------------------------- 3 NOTE: I'm unsure how to graph the symbol for principle square root. I hope this makes sense.

4w - 1 w - 1 w - 1 ------- - --------- = -------- 3w + 6 3 w + 2

A wholesaler prices the best latex flat paint at _15x_ x - 1 dollars per gallon where x is the number of gallons ( x > 1). The more you buy, the lower the price will be per gallon. As you buy more and more gallons, what price per gallon does the paint approach?

Solve the following equation for x . Write the answer as a fraction in simplest form. -7 (x-8) = 5x + 3 + 5 (-6x + 4)
