B, short explanation remember the sets are set up like (x,y) in a set there should be no matching x points so if it matches it's not a function :)
long explanation: these are (x,y) sets {(0,3), (3,0), (0,4), (4,0)} the first choice shows that there are two X solutions <span>if they are equal to 0 (0,3) (0,4) so this cant be a function.
second choice</span><span> {(0,2), (2,0), (4,6), (6,4)} does not have two X solutions so this is a function third choice</span>{(2,6), (3,6), (4,6), (2,0)} has two X solutions if x is equal to 2 and the last choice <span>{(6,2), (2,0), (4,6), (6,4)} has two X solutions if x is equal to 6 hope i helped! if i did please give me brainlest :) </span>
3. area=legngth tiimes width legnth is 10 more than 2 times width l=10+2w lw=area=(10+2w)w=10w+2w^2 area=3600 3600=10w+2w^2 so divide by 2 1800=5w+w^2 subtract 1800 from both sides (note they used x instead of w) 0=w^2+5w-1800 then the facotred form is (w-40)(w+45)=0
0 product property measn if you have xy, then x and or y =0
therefor w-40=0 and w+45=0 w=40 or -45 discard negative because negative legnth is not possible
explian how solution relates to situation it is math so it is correct because we represented it corrrectly
the other solution is because of math and eliminate negative legnth becasue tha tis not possible basically because we represented it correctly not a very clear quetion to answer
basically 'because it represents the solution so we solved it and it is correct'
Since you have to mix all of it together, the whole cocktail is 20+10+15=45. And the portion that is coconut milk is 15ml. So that means there is 15 out of 45 or 15/45 coconut milk in the cocktail. Then the simpelest form is 1/3.
