Situation: Find the substance's half-life, in days.
Round your answer to the nearest tenth.
A 42 gram sample of a substance that's
used to treat thyroid disorders has a k-
value of 0.126.
Enter the correct answer.
-kt
N = Noe
DONE
No = initial mass (at time t = 0)
N = mass at time t
k= a positive constant that depends on
the substance itself and on the units
used to measure time
t = time, in days

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
