Determine the slope and the y-intercept of the line. Express numbers as integers or simplified fractions. 1/5y=-4

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

a = 11 : 4

b = 38

c = 1 for every 6

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
