A man collected data on his weight loss while on a diet. He modeled the equation y = 295 − 5x for the line of best fit. The independent variable, x, is time in weeks and the dependent variable, y, is weight in pounds. What does the y-intercept mean in this context? A) The man lost 5 additional pounds each week. B) The man lost a total of 5 pounds while on his diet. C) The man weighed 295 pounds at the start of his diet. D) The man lost a total of 295 pounds while on his diet.

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)

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
