Could someone please please please help me?!! I seriously have a hard time doing this. Please use either the substitution method or the quadratic formula, but preferably the substitution method. xy + y = 2
2x + y = 3

Which of the following is a proper fraction? a. 9⁄8 b. 5⁄6 c. 7⁄3 d. 4⁄2

Plz hurry evaluate the expression a+b where a=8 and b=19

How do you find p(a and b) if a and b are independent events for two or more actions, such as tossing a coin twice and finding p(heads and heads)? 2. how do you find p(a or b) if a and b are independent events for one action, such as spinning a four-color spinner once and finding p(red or blue)?
