7 0

Answer:

Graph A

Step-by-step explanation:

For a relation to be said to be a function, each x-value must have exactly one y-value assigned to it. That is, no domain value has two different range value assigned to it.

Therefore, graph A is a function, because exactly 1 range value is assigned to each domain value.

Find the area of the polygon.
Anettt [7]

Answer:

option D: 27.5 square units

Step-by-step explanation:

Divide the polygon in 6 figures

see the attached figure

Area of figure 1 (right triangle)

A1=(1/2)(3)(3)=4.5 units²

Area of figure 2 (rectangle)

A2=(1)(3)=3 units²

Area of figure 3 (rectangle)

A3=(1)(3)=3 units²

Area of figure 4 (right triangle)

A4=(1/2)(3)(3)=4.5 units²

Area of figure 5 (right triangle)

A5=(1/2)(4)(5)=10 units²

Area of figure 6 (right triangle)

A6=(1/2)(1)(5)=2.5 units²

The total area is equal to

At=A1+A2+A3+A4+A5+A6

At=4.5+3+3+4.5+10+2.5=27.5 units²
