Awindow is in the shape of a rectangle with a base of 4 ft and a height of 5 ft. the window has a colored glass in the shape of a kite. use the grid to identify the area of the colored glass.

Step-by-step explanation:

Look at the picture.

A₁ = 2 · 2 = 4

A₂ = 2 · 3 = 6

The area of a rhombus:

A = A₁ + A₂ ⇒ A = 4 + 6 = 10

You can use the formula of an area of a rhombus:

d₁ = 4, d₂ = 5

Substitute:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

y -5 = (-1/4)(x + 8)
