Find four solutions of the given function. write the solutions as ordered pairs. 4x – y = 4

see below

Step-by-step explanation:

4x - y = 4 (rearrange)

y = 4x -4

to find 4 solutions, just randomly choose four values of x and find the corresponding values of y for each.

Lets choose x = 0, 1, 2 and 4

x = 0, y = 4(0) -4 = -4 > Hence (0,-4) is a solution

x = 1, y = 4(1) -4 = 0 > Hence (1,0) is a solution

x = 2, y = 4(2) -4 = 44 > Hence (2,4) is a solution

x = 3, y = 4(3) -4 = 8 > Hence (3,8) is a solution

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:
