I really lost my brain cell trynna do this someone help me please !

Here:

Step-by-step explanation:

x is how much she spends, y is how much she saves.

for c, you can write:

y = 300, x = 0

y = 200, x = 100

y = 100, x = 200

y = 50, x = 250

y = 1, x = 299

x and y are variables because they can vary depending on one or the other.

The formula is just a relation between x and y. For example, another way can be that I give you $10 and you buy me 5 bottles of water. But if I give you $20, you will buy 10. The amount I give you and the number of bottles you buy me are both dependent and they have a relationship no matter what value they are. And the relationship is described by the function in the question.

answer:     true

step-by-step explanation:

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)
