Answer:
The slope is -1/4
Step-by-step explanation:
perpendicular line is 
Slope formula : (y2 - y1) / (x2 - x1)
(2,4)...x1 = 2 and y1 = 4
(5,10)...x2 = 5 and y2 = 10
now we sub and solve
slope = (10 - 4) / (5 - 2) = 6/3 = 2
The slope of the line is 2....and this is basically saying that Jan runs 2 laps every minute

Answer:
Given:
In Rhombus QRST, diagonals QS and RT intersect at W and U∈QR and point V∈RT such that UV⊥QR. (shown in below diagram)
To prove: QW•UR =WT•UV
Proof:
In a rhombus diagonals bisect perpendicularly,
Thus, in QRST
QW≅WS, WR ≅ WT and m∠QWR=m∠QWT=m∠RWS=m∠TWS=90°.
In triangles QWR and UVR,
(Right angles)
(Common angles)
By AA similarity postulate,

The corresponding sides in similar triangles are in same proportion,


(∵ WR ≅ WT )
Hence, proved.
Answer:
True
Step-by-step explanation:
There are an odd number of negative signs (3)
If there is an odd number it is negative, but if it is even then the result will be positive
Here's a deeper explanation
-1 times -1 is simply 1
Then 1 times -1 is -1
Our final answer is -1 so this is true.
