Answer:
The answer is B or (-infinity,2]
Step-by-step explanation:
Just took it on edge 2020. You could also double check this answer by graphing it on desmos.
The solution set of the equation 8(2x – 3) ≤ 20 – 4x is (–∞, 2].
Inequality
What is inequalities?
A difference between two values indicates whether one is smaller, larger, or simply not equal to the other.
a ≥ b means that a is greater than or equal to b.
What is interval?
Any real number that lies between any two numbers in the interval set of real numbers is included in the set.
Calculate the interval:
The given equation is,
=> 8(2x – 3) ≤ 20 – 4x
=> 16x - 24 ≤ 20 - 4x
=> 16x + 4x ≤ 20 + 24
=> 20x ≤ 44
=> x ≤ 2.2
Therefore the value of 'x' must be less than or equal to 2.2, which is satisfied by the interval (–∞, 2].
