Answer:

Step-by-step explanation:

hello :

The east edge cannot intersect with the west edge so :

the west edge and The east edge are paralal same slope but the slope for the line y = 2x + 5 is : 2

so : the line could the east edge be located is : y= 2x+b b : no 5

1. Homer has an idea for a new donut shop. He wants to design the donut shop so that the rectangular

Tju [1.3M]

Solving a system of equations, it is found that since the quadratic equation has two positive roots, they can be the values of the length and the width, and the design is possible.

The perimeter of a rectangle of length l and width w is given by:

$P = 2(l + w)$

The area is:

$A = lw$

In this problem, perimeter of 63.5 m, hence:

$2l + 2w = 63.5$

$2l = 63.5 - 2w$

$l = 31.75 - w$

Area of 225 m², hence:

$lw = 225$

$(31.75 - w)(w) = 225$

$w^2 - 31.75w + 225 = 0$

Which is a quadratic equation with coefficients $a = 1, b = -31.75, c = 225$ .

Then:

$\Delta = b^2 - 4ac = (-31.75)^2 - 4(1)(225) = 108.0625$

$w_1 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{31.75 + \sqrt{108.0625}}{2} = 21.1$

$w_2 = \frac{-b - \sqrt{\Delta}}{2a} = \frac{31.75 - \sqrt{108.0625}}{2} = 10.68$

Since the quadratic equation has two positive roots, they can be the values of the length and the width, and the design is possible.

How do i identify the slope in a math question?

Thepotemich [5.8K]

Answer:

y=mx+b is the equation for a line, x and y being coordinates, m as your slope and b as your y intercept. Slope is rise over run.
