Answer:
The period of Y increases by a factor of 
with respect to the period of X
Step-by-step explanation:
The equation 
shows the relationship between the orbital period of a planet, T, and the average distance from the planet to the sun, A, in astronomical units, AU. If planet Y is k times the average distance from the sun as planet X, at what factor does the orbital period increase?
For the planet Y:
For planet X:
To know the factor of aumeto we compared 
with 
We know that the distance "a" from planet Y is k times larger than the distance from planet X to the sun. So:
So
Then, the period of Y increases by a factor of with respect to the period of X
Answer:
line 1
Step-by-step explanation:
because
3x + 2y + z = 11 ➡ z = 11 - 3x - 2y
3x and 2y must change sign when transfer to other sid eof equation
