2 numbers can be represented by the variables x and y.
Set up a system of equations:
The two numbers added together will result in a sum of 37. However, one number subtracted from another will result in a difference of 31.
In both systems of equations, there are inverses of variable y. Therefore, we can combine the systems of equations by adding them together:
Divide both sides by 2 to get x by itself:
One of the numbers will be 34.
Plug the value into one of the equations:
Subtract 34 from both sides to get y by itself:
The two numbers that sum up to 37, with a difference of 31 between them, will be 3 and 34.
ANSWER
I) 5:11
ii) 5:11
iii) 125:1331
EXPLANATION
Let the side lengths be in the ratio:
x:y
This implies that the area will be in the ratio:
Take positive square root.
Hence the sides are in the ratio:
x:y=5:11
The perimeter of the smaller hexagon is 6×5=30
The perimeter of the larger hexagon is 6×11=66
The ratio of the perimeter is
30:66=5:11
The volume will be in the ratio
5³:11³
125:1331

Answer: I have done this assingment question before the inverse varitation is D at first while looking at it you would think its C but thats what they try to do to test your stuff goodluck
Step-by-step explanation:
The equation is y = -1/5x + 1
