Final answer:
The pairs of equivalent expressions in this question are: a) y - 0.327 = y + 0.327 b) y - 1/y = y + By c) 5y > 0.687 d) y + By > 1.327. To match these pairs, we can combine like terms, eliminate denominators, and simplify inequalities.
Step-by-step explanation:
The pairs of equivalent expressions in this question are:
-
To match these pairs, let's break down each expression:
a) To get the equivalent expression, we can combine the y terms and the constant terms: y - 0.327 + 0.327 = y + 0.327.
b) To get the equivalent expression, we can multiply both sides of the equation by y to eliminate the denominator: y^2 - 1 = y + By. This can be rewritten as y - 1/y = y + By.
c) To get the equivalent expression, we can divide both sides of the inequality by 5: y > 0.687/5, which simplifies to y > 0.1374.
d) To get the equivalent expression, we can subtract y from both sides of the inequality and then divide by B: y + By - y > 1.327 - y, which simplifies to By > 1.327 - y.
