The answer would be the bottom left one because 5.15 round to 5 and 42,980 rounds to 40,000 which is equal to 4x10^4 (4 zeros). Then you subtract the exponents and divide the other terms to get 1.25x10^2

Answer:
x = 4
Step-by-step explanation:
1. 8x+1 = 33 and the 4x together
2. 8x = 32 subtract 1 from each side
3. x = 4 Divide both sides by 8
No that is an inverse variation, a direct variation must have a y that is directly proportional to x while the picture shows a y that is inversely proportional to x <span />

Answer: n^2 + 1</h3>
Explanation:
Imagine that you cross out the top-most square for each step of each diagram. The squares not crossed out have the following counts: 1, 4, 9
This is the sequence of perfect squares. So the rule will have us take the number n, and square it to get n^2. Then we add on the squares we crossed out earlier. This explains the "plus 1" at the end to get the answer of n^2+1
