12) Bob and Stu think that ginger can increase intelligence. So they build a simple maze, and record the times of 6 lab rats running through. Over a period of 3 days they increase ginger intake on each day, and re-measure the maze times. Each rat is tested once each day. As incentive, the rats are deprived of food for 5 hours before each test, and tasty rat food is placed at the end of the maze each time. Bob and Stu find that running time decreases each day. They thus conclude that ginger increases intelligence. find the independent and dependent variable

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

answer: sensy

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
