then difference between the cubes of two numbers is twice the value of the perfect square of a possitive Intiger
PSYCHO15rus [73]
There are many solutions. But what do you mean with a perfect square of a number. I thought a number IS a perfect square or not.

For example, the difference between 2² and 4² = 12, which is twice the number 6, which is √36

The difference between 2² and 6² = 32, which is twice the number 16, which is a perfect square.

So choose depending on your interpretation of the question... ;-)

On Chris's birthday in 1992, he was half the age of his brother Joseph. On Chris' birthday in 1998, he was two-thirds the age of
aev [14]
Suppose in 1992 Chris was x years old, his brother was then 2x years old.
6 years later in 1998, Chris is (x+6) years old, his brother is (2x+6), 
(x+6)=(2/3)(2x+6)
x+6=(4/3)x+4
(4/3)x-x=6-4
(1/3)x=3
x=6
in 1992, Chris was 6, so in 2018 he will be 6+(2018-1992)=32 years old.

Write an equation that gives the proportional relationship of the graph.
viktelen [127]

The required equation is: y= 7x

Option C is correct.

Step-by-step explanation:

The proportional relationship can be found using the equation: y=k\,x

where x and y are the points and k is the constant of proportionality.

We need to find k.

From the graph given, we can locate points x and y:

x=5, y= 35 then k would be:

y=kx\\k=y/x\\k=35/5\\k=7

x=10, y=70 then k would be:

y=kx\\k=y/x\\k=70/10\\k=7

For each values of x and y, the constant of proportionality k is 7

So, the required equation is: y= 7x

Option C is correct.
