Line a passes through points (0,4) and (1,7). Line b passes through points (2,1) and (6,4). Which of the following statements are true? The statements are A. Line a and b intersect at poin (0,0). B. Lines a and b intersect at point (-2,-2). C. Lines a and b intersect at point (3,3/4) or D. Lines a and b do not intersect

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:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

its totaly b
