Question on: JAMB Mathematics - 2007
A binary operation (\oplus) on real numbers is defined by x (\oplus) y = xy + x + y for any two real numbers x and y. The value of (-(\frac{3}{4})) (\oplus) 6 is
A
-\(\frac{3}{4}\)
B
\(\frac{45}{4}\)
C
-\(\frac{4}{3}\)
D
\(\frac{3}{4}\)
Ask EduPadi AI for a detailed answer
Correct Option: D
x (\oplus) y = xy + x + y
(-(\frac{3}{4})) (\oplus) 6 = -(\frac{3}{4.6}) - (\frac{3}{4}) + 6
= -(\frac{9}{2}) - (\frac{3}{4}) + 6
= -(\frac{3}{4})
