Which best describes the rate of change?

167

Step-by-step explanation:

2500÷15=166.666667

Round it up to 167

*I used 2500 and 15 because that's a point (15,2500) that you can see very clearly on the graph*

Solution: A rhombus abcd  whose area is 72 square units.

Diagonals ac and bd intersect each other at point e.

Also, db= x-1,

ec = 8 units, so, ac=16 units → as diagonals of rhombus bisect each other.

→Area of Rhombus = 1/2 × Product of Diagonals

→ 72 = 1/2×16×(x-1)

→144= 16 (x-1)

Dividing both sides by 16,we get

→ x-1=9

→ x=9+1

→ x=10 units
