Based on the given variation, y does not vary directly with x and the constant of variation are 8, 3.2 and 1.25 respectively.
<h3>Variation</h3>
y = k × x
where,
k = constant of proportionality
y = -40
x = -5
y = k × x
-40 = k × -5
-40 = -5k
k = -40/-5
k = 8
when,
y = 8 and x = 2.5
y = k × x
8 = k × 2.5
8 = 2.5k
k = 8/2.5
k = 3.2
when,
y = 5 and x = 4
y = k × x
5 = k × 4
5 = 4k
k = 5/4
k = 1.25

Answer:
14 lb
Step-by-step explanation:
10^3 = 1000
14,000 lb/1000 = 14 lb
Since the weight of the elephant is 1000 times the weight of the cat, then the weight of the cat is one-thousandth of the weight of the elephant. To find one-thousandth of a number, divide the number by 1000. 14,000 lb divided by 1000 is 14 lb.
P.S. I feel much better for the cat.
