V THIS SECTION Q1. A binary operation is defined on the set R, of real numbers by x*y=x+y+8, where x, y ER.
a) Calculate 6 * (85) b) Determine whether or not the operation is i) commutative ii) associative
c) find the identity element of the operation d) find the inverse under 6.​

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
