a chef needs 6 L of a solution that is 70% of sugar. he has a 30% sugar mixture and an 80% sugar mixture that he can combine to the 70% mixture. let X represent the number of the liters of the 30% sugar mixture and let Y represent the number of liters of the 80% sugar mixture. how many liters of 30% sugar mixture is there?

1.2 litres of the 30% solution.

Step-by-step explanation:

0.30x + 0.80y = 0.70(x + y)

0.30x - 0.70x + 0.80y - 0.70y = 0

-0.40x + 0.10y = 0

Also

x + y = 6

Multiply the third equation by 10:

-4x + y = 0

Subtracting the last 2 equations:

5x = 6

x = 6/5 = 1.2 litres.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

a natural event such as a flood, earthquake, or hurricane that causes great damage or loss of life.
