Find the equation (in terms of x ) of the line through the points (-2,4) and (2,-8)

step-by-step explanation:

their are no angles. sorry cant .

just go here

its what i use

step-by-step explanation:

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
