what does the slope of -1 tell you about thr relationship between lengths and widths of rectangles with perimeter 24?

NeX [460]

Using linear function concepts, the slope of -1 means that when one of the length/width is increased by 1, the other is decreased by 1.

<h3>What is a linear function?</h3>

A linear function is modeled by:

$y = mx + b$

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0.

In this problem:

The lengths and the widths are interchangeable, that is, either can be considered as the input or as the output.

The slope of -1 means that when the input in increased by 1, the output is decreased by -1, that is, when one of the length/width is increased by 1, the other is decreased by 1.

Point H is the midpoint of FG. What is the value of y?

Delicious77 [7]

The value of y is 17/5.

<h3>What is Midpoint?</h3>

A midpoint is defined as in the middle of the line connecting two points a position known as a midpoint. A location in the middle of a line connecting the two points that are equally far from both points is the midpoint.

Let two points A (x₁, y₁) and B (x₂, y₂), the midpoint between A and B is given by,

M(x, y) = (x₁ + x₂)/2, (y₁ + y₂)/2

Given that H is the midpoint of FG

G(4x, 6y + 6), H(4, 15) and F(2y+2, 2x+4)

⇒ (4x+2y+2)/2 = 4 and (6y+6+2x+4)/2 = 15

⇒ (4x+2y+2) = 8 and (2x+6y+10) = 30

⇒ 4x+2y = 6 and 2x+6y = 20

⇒ 2x+y = 3 and x+3y = 10

⇒ x = 10 - 3y

Substitute the value of x into 2x+y = 3

⇒ 2(10 - 3y) +y = 3

⇒ 20 - 6y +y = 3

⇒ 5y = 17

⇒ y = 17/5
