Which of the following would show that the diagonals of quadrilateral DEFG on the coordinate plane are perpendicular?

A. Show that slope of DF¯¯¯¯¯¯ = slope of EG¯¯¯¯¯¯.
B. Show that midpoint of DF¯¯¯¯¯¯ is the same as midpoint of EG¯¯¯¯¯¯.
C. Show that DF = EG.
D. Show that (slope of DF¯¯¯¯¯¯)(slope of EG¯¯¯¯¯¯) = –1.

DF = 5x - 3 = 5(2) - 3 = 10 - 3 = 7 ; DF = 7

EG = x + 5 = 2 + 5 = 7 ; EG = 7

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

in 2010, the population of the state of california is 37.29 × 10⁶

step-by-step explanation:

population of los angeles = 3.79 × 10⁶

population of california = 9.84 × population of los angeles

                                        = 9.84 × 3.79 × 10⁶

                                        = 37.2936 × 10⁶

                                        = 37.29 × 10⁶

∴ in 2010, the population of the state of california is 37.29 × 10⁶
