LaTeX: d=\sqrt{\left(x_2+x_1\right)-\left( y_2+y_1\right)} d = ( x 2 + x 1 ) − ( y 2 + y 1 )

LaTeX: d=\sqrt{\left(x_1-x_2\right)^2+\lef t(y_1-y_2\right)^2} d = ( x 1 − x 2 ) 2 + ( y 1 − y 2 ) 2

LaTeX: d=\sqrt{\left(x_2+x_1\right)^2+\lef t(y_2+y_1\right)^2} d = ( x 2 + x 1 ) 2 + ( y 2 + y 1 ) 2

LaTeX: d=\sqrt{\left|x_2-x_1\right|^2+\lef t|y_2-y_1\right|^2} d = | x 2 − x 1 | 2 + | y 2 − y 1 | 2

LaTeX: d=\sqrt{\left(x_2-x_1\right)^2+\lef t(y_2-y_1\right)^2}

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

$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

answer: it is a.,b.,d.
