25.5 is to the nearest tenth. It is one decimal place out
Method 1:By graphing, we can find the graph of y = 5log(x + 3) and y = 5 to see where they intersect.
Method 2:Alternatively, by subtracting 5 from both sides, we can find where the graph 5log(x + 3) - 5 hits the x-axis. In essence, we are finding when y hits 0 and thus, finding where it hits the x-axis.
Method 3:We can also just solve this algebraically. When we don't have any superscripts, we take the assumption that we're working in base 10.
Divide both sides by 5:
Take the inverse of log(x + 3) to both sides:
Hence, we know that at x = 7, 5log(7 + 3) = 5.
The graphs of Method 1 is pictured first, and the graph of Method 2 is pictured on the right.
The answer might be 45 x 1, because 45 is the greatest factor of 45.
If you want to know why tell me
1) 12, 14
This is the answer because each increasing number was increased by 2, so if you add 2 to 10, you'd get 12. If you add 2 to 12, you would get 14.
2) 50, 54
Same explanation as above but for the number 4.
3) 68, 50
Same explanation as 1, but with subtracting the number 6.
4) 67, 69
Same as number 1
5) 103, 101
Same as number 3 but subtracting the number 2
Hope this helps!!! :)
