Answer:

y = 6 * 3ˣ

Step-by-step explanation:

y = a * bˣ

(-1 , 2):   2 = a * (b)⁻¹ = a/b               a = 2b

(2 , 54)  54 = a * b²  = 2b * b² = 2b³

b³ = 54/2 = 27          b = 3

a = 6

Function: y = 6 * 3ˣ

Answer:

-13 1/2 < -6/8

Step-by-step explanation:

*Any negative in either the numerator or denominator will make the entire fraction negative.

1/2  = .5

-13 1/2 = -13.5

-6/8 = -3/4

-3/4 = -0.75

-6/8 = -0.75

-13 1/2 = -13.5

Which means:

-13 1/2 < -6/8

Hope this helped.

A rectangular field is ten times as long as it is wide. If the perimeter of the field is 1320 feet, what are the dimensions of t
inn [45]

The equation is P = 2 ( L + W )

The width of the field is 60 feet.

The length of the field is 600 feet.

Given,

A rectangular field is ten times as long as it is wide.

The perimeter of the field is 1320 feet.

<h3>What is the area of a rectangle?</h3>

Area of rectangle = Length x wide.

Perimeter = 2 ( Length + width )

Let the length of the rectangle be L

Width = W

L = 10W

Perimeter + 2 ( L + W )

1320 = 2 ( 10W + W )

Divide it by 2 into both sides.

1320/2 = 2/2 x 11W

660 = 11W

Divide both sides by 11.

660/11 = 11/11 W

60 = W

W = 60 feet

L = 10W = 10 X 60 = 600 feet

L = 600 feet

Thus,

The equation is P = 2 ( L + W )

The width of the field is 60 feet.

The length of the field is 600 feet.
