In a science experience a plant grew 3/4 inch one week and 1/2 inch the next week. Use a common denominator to write an equivalent fraction for each fraction.

X+2y=-1 and 4x-4y=20 solve by substitution

Expended form 1.87268

Log (10 - 4. x) = log (10 - 3x)

The method of Problem 20 can be extended to second order equations with variable coefficients. If y1 is a known nonvanishing solution of y′′ + p (t) y′ + q (t) y = 0, show that a second solution y2 satisfies (y2 / y1) ′ =
