<span>y = 50x/(x+33)
x≠-33
xy + 33y = 50x
33y = x(50-y)
33y/(50-y)= x

or y≠50

=> yϵ R - {50} </span>

What is the area of this figure? Please help
iragen [17]

Answer:

369.5 ft²

Step-by-step explanation:

Separate the figure into 2 rectangles and 2 triangles.

(see attached image)

<u>Area 1</u>

Area of a rectangle = width × length

                                 = 4 × 5

                                 = 20 ft²

<u>Area 2</u>

Area of a rectangle = width × length

                                 = 8 × (4 + 4 + 5)

                                 = 8 × 13

                                 = 104 ft²

<u>Area 3</u>

Area of a triangle = 1/2 × base × height

                             = 1/2 × (6 + 4 + 5 + 4 - 6) × 23

                             = 1/2 × 13 × 23

                             = 149.5 ft²

<u>Area 4</u>

Area of a triangle = 1/2 × base × height

                             = 1/2 × 8 × (21 + 8 - 5)

                             = 1/2 × 8 × 24

                             = 96 ft²

<u>Total Area</u>

Area 1 + Area 2 + Area 3 + Area 2 = 20 + 104 + 149.5 + 96

                                                        = 369.5 ft²

Find the coordinates of the midpoint of line segment lb if l (8, 5) and b (-6, 2).
jeyben [28]

Answer:

The coordinates of the midpoint of the segment is (1,3.5)

Step-by-step explanation:

In this question, we are concerned with finding the coordinates of the mid point of the line that joins segment lb

To do this, we shall be using the midpoint formula;

(x,y) = (x1 + x2)/2, (y1 + y2)/2

Where (x1,y1) = (8,5)

(x2,y2) = (-6,2)

Thus;

(x, y) = (8 + (-6))/2, (5 + 2)/2

(x ,y) = (2/2), (7/2)

(x,y) = (1,3.5)
