Question

a college board began reporting exam scores with a new scale in 2002, with the new scale score ( y ) defined as a function of the old scale score ( x ) by the equation ( y = 0.89x + 126.5127 ). suppose the college requires a new scale score greater than or equal to 1500 to admit a student. to determine what old score values would be equivalent to the new score that would result in admission to this college, complete parts (a) and (b).
(a) write an inequality in terms of ( x ) to represent the problem.
(type an inequality. do not simplify.)

Explanation:

Step1: Define target new score

The new score $y$ needs to be $\geq 1500$.

Step2: Substitute y's expression

Replace $y$ with the given function of $x$.
$0.89x + 126.5127 \geq 1500$

Answer:

$0.89x + 126.5127 \geq 1500$
