A reflection over the y-axis would be mapped algebraically as: O (x, y) → (y, x)
O (x, y) → (x,-y)
O (x, y) → (-x, y)

según la Organización Mundial de la Salud la calidad de la vida depende de lo siguiente excepto

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
