To solve this, you want to isolate h. Start by subtracting 9 from both sides: 16 = -3.2h. Divide by -3.2: h = -5

Answer:
Your answer is -6 over 15
Step-by-step explanation:
Use the formula y2-y1 over x2- x1 to solve the slope. Then plug in your numbers. It would be 1- 7 over 10 - (-5). This equals -6/15, which would be the slope.
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.
