They all 3 have no solution!
Answer:
x=15 y=24
Step-by-step explanation:
This is because the rule is x goes up 3 y goes up 4
(9,12)->(x,20)
it skips one, so instead of adding 3 we add six
x=15
(15,20)->(18,y)
you follow the rule and 4.
Y=24

64 ounces of a 2% salt solution contains 1.28 ounces of salt and thus 62.72 ounces of water.
The mass of the 10% solution is (x+1.28), where x is the mass of water.
1.28 divided by (x+1.28) must be equal to 10%.

The 10% solution contains 11.52 ounces of water.
51.2 ounces of water must be evaporated.
Answer:
the graph of this function has no local extrema
Step-by-step explanation:
A 5th-degree polynomial graph will have a maximum of 4 local extrema, in general. However, this function has none. The derivative of this function is positive everywhere, so there are no extrema.
