An equation can be used to find the total cost of buying square-foot floor 5 points tiles to cover an area of floor. Using the table below, find the equation that
best represents y, the total cost, as a function of x, the number of square
feet to be covered. *
Number of Square Feet (x) Total Cost (y)
1800
$720
2300
$920
2900
$1,160
Ox=0.4y
O y=0.4x
x=2.5y

it could be 720

Step-by-step explanation:

a box 3 3/4 feet long or 4+ feet.

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)
