Audrina constructed a proof that quadrilateral PQRS is a rectangle.
In the proof below, she started with a pair of observations about the plot of quadrilateral PQRS on the coordinate plane.
With which pair of observations did Audrina start her proof?
A) Slope of PQ = Slope of RS = 3 ; Slope of PS = Slope of QR = 1/3
B) Slope of PQ = Slope of RS = 3: Slope of PS = Slope of QR = − 1/3
C) PQ = RS = 2√10 ;PS = QR = √17
D) PQ = RS = 6; PS = QR = 4

B) Slope of PQ = Slope of RS = 3: Slope of PS = Slope of QR = − 1/3

Step-by-step explanation:

slope PQ =3 and -1/3 is the slope of its perpendicular line

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
