Inessa [10]

It is given in the question , that Simon has 160 meters of fencing to build a rectangular garden. the garden's area (in square meters) as a function of the garden's width w (in meters) is modeled by

A(w) = -w(w-80)
\\
A(w) = -w^2 + 80w

Which represents parabola and the parabola is maximum at its vertex, that is

w = -\frac{b}{2a} = - \frac{80}{2} = 40 meters

Therefore the width is 40 meters and the area is

A(40) = -40(40-80) = -40*-40 = 1600 meter ^2

SOMEONE PLS HELP :( I WILL CHOOSE BRAINLIEST!!!
Nikolay [14]

Answer:

x -3y = - 3

Step-by-step explanation:

Slope of line m = (0 -1 )/(-3 - 0) = 1/3

y - intercept b = 1

Equation of line in slope-intercept form is given as:

y = mx + b

Plugging m = 1/3 and b = 1 in the above equation, we find:

y = 1/3 x + 1

-> 3y = x + 3

-> x -3y = - 3

This is the required equation of line.
