A miniature golf course has a special group rate you can pay $20 +3 per person when you have a group of five friends let F the number of friends a C the total cost of time in which variable is independent and which is dependent on right in equation that models the situation to make a table shows the cost of 5to 12 friends

Step-by-step explanation:

The problem statement tells you the definitions of the variables, and that cost depends on the number of friends. Thus cost (C) is the dependent variable, and the number of friends (F) is the independent variable.

  cost = $20 + $3 × (number of friends)

  C = 20 + 3F

You can make a table by doing the calculations for F = 5, 6, ..., 12. This can be made easier if you realize that each friend above 5 adds $3 to the cost.

5/12, or 5: 12

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)
