x is strictly less than 2 or x ∈ (-∞, 2)
Given: inequality 5x - 7 < 2x - 1
What are inequalities?
Inequalities are statements that are represented as comparison between two or more numbers or algebraic expressions.(strictly less, strictly great, greater, lesser)
Solving the given equation:
5x - 7 < 2x - 1
=> 5x - 7 - 2x < 2x - 1 - 2x
=> 3x - 7 < -1
=> 3x - 7 + 7 < -1 + 7
=> 3x < 6
=> x < 2
Therefore, x is strictly less than 2.
Hence x ∈ (-∞, 2)

Recall that m(t) = m.(1/2)^t/h for radioactive decay, where h is the half-life. Suppose that a 500 g sample of phosphorus-32 decays to 356 g over 7 days. Calculate the half life of the sample.
<u>Answer:</u> The half life of the sample of phosphorus-32 is
<u>Step-by-step explanation:</u>
The equation used to calculate the half life of the sample is given as:
where,
m(t) = amount of sample after time 't' = 356 g
= initial amount of the sample = 500 g
t = time period = 7 days
h = half life of the sample = ?
Putting values in above equation, we get:
Hence, the half life of the sample of phosphorus-32 is
