The ordered pairs (6,8), (9, 12), (x, 20), (18, y) represent a proportional relationship. Find the value of X and the value of Y
sasho [114]

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

How much water must be evaporated from 64 ounces of a 2% salt solution to make a 10% salt solution?
Rufina [12.5K]
64 \times 2\%=64 \times 0.02=1.28
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%.
\frac{1.28}{x+1.28} \times 100\%=10\% \\
\frac{1.28}{x+1.28} \times 100=10 \\
1.28 \times 100=10(x+1.28) \\
128=10x+12.8 \\
115.2=10x \\
x=11.52

The 10% solution contains 11.52 ounces of water.
62.72-11.52=51.2

51.2 ounces of water must be evaporated.

What is the maximum number of relative extrema contained in the graph of this function?
Savatey [412]

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.
