Final answer:
The given sentence is written as the equation y = 14x + 2000, showing a fixed cost of $2,000 and a variable cost of $14 per unit. Similarly, the equation (3+5) - (4/5) = x + 3 translates to a sentence using the sum of numbers and the variable x.
Step-by-step explanation:
The sentence "The linear expression of a company’s operating cost when the fixed cost, also known as the constant, is two thousand and the per unit cost is fourteen" translates into an equation as y = 14x + 2000, where y represents the total operating cost and x represents the number of units produced. The fixed cost here is $2,000 and the variable cost per unit is $14.
Moving on to the second part, the equation (3+5) - (4/5) = x + 3 can be articulated as follows: The sum of three and five, diminished by four-fifths, equals the variable x increased by three.
