Final answer:
To determine if the two expressions are equivalent, we substitute t=2 and t=6 into the expressions and compare the results. The correct answer is D. The expressions are not equivalent.
Step-by-step explanation:
To determine if the two expressions are equivalent, we substitute t=2 and t=6 into the expressions and compare the results.
Expression 1: 1₁ = 6 - 21₁ + 22.5 - 31₁ = 28.5 - 51₁
Expression 2: 11
Substituting t=2 into both expressions:
Expression 1: 28.5 - 51(2) = 28.5 - 102 = -73.5
Expression 2: 11
Since the values are not equal, we can conclude that the expressions are not equivalent. Therefore, the correct answer is D. The expressions are not equivalent.
