Put it on the graph as 2xy=10!
Yes..it does. To be a function, all the inputs (x's) have to be different numbers...there can be no repeating x's...there can be repeating outputs (y's)...just not the x's
Answer:

Step-by-step explanation:
Hello!
Let's use the square root property to solve this question
Solve:
The answer is option A: x = ±2√3
4/3 because 3/3 is 1 and 4/3 is 1 1/3
We should use lb to convert weight to kg
let unknown lb be = X
14 lb = 1 stone
X lb = 9 stone
Cross multiply : X × 1 = 9 × 14
X = 126 / 1 = 126 lb
9 stone = 126 lb
let unknown value of kg be = Y
2.2 lb = 1kg
126 lb = Y kg
Cross multiply : 2.2 × Y = 126 × 1
Y = 126 / 2.2 = 57.3 kg
So 9 stone = 126 lb = 57.3 kg
HOPE IT HELPED !!
