Please help me! Perform these transformations on △ DEF. (a) Reflect △ DEF across the x-axis and label the resulting image△ D′E′F′.
(b) Rotate △ D′E′F′ 90° clockwise about the origin and label the resulting image △ D′′E′′F′′.
(c) Translate △ D′′E′′F′′ according to (x, y) → (x − 2, y + 2) and label the image △ D′′′E′′′F′′′.

could you reply to this with the question so i can ?

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
