Step-by-step explanation:
<u>The scale factor is </u>
- 1 : 9.5×10²⁰ as we make our galaxy as small as 1 m.
<u>The distance to Andromeda would be:</u>
- 2.4×10²² * 1/9.5×10²⁰ =
- 2.4/9.5×10²²⁻²⁰ =
- 0.25×10² =
- 25 m

<span>The correct answer is that y does not vary directly with x.
Explanation<span>:
If y varies directly with x, this means that it would fit the equation y=kx for every point in the set.
For the first point, we would have 11=7k; this would mean that k=11//7.
For the second point, we would have 13=8k; this would mean that k=13/8.
Checking using proportions shows us that 11/7 does not equal 13/8:
cross multiply, and you have 11*8=7*13, or 88=91.
This is not true, so k is not a constant, and y does not vary directly with x.</span></span>
