I need help. I have no idea how to do this!

A ≈ 5.1 units²

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = × 2 sides × sin (angle between them ) , then

A = 0.5 × 7 × 3 × sin29° ≈ 5.1 units²

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
