The first one is no solution, the second one is t+x=y
A:-) would be the correct answer because if 2/5 is 1/2 they size of 5 it would have to be 2/2-1/2.
Linear simply means the higest power of any placeholder is 1 and positive
first one, all 1, linear, A
2nd one
that is actually 6y^-1, that is negative exponent so not linear, so B
3rd one: correct, that is just x^1 times 1/2 minus 3 so linear, so A
4th one, x^3, duh, not 1, non-linear, B
5th one, fist degree, linear, A
A
B
A
B
A
The change of base formula allows you to write a logarithm in terms of logarithms with another base. It follows this pattern,

where a≠1 and b≠1
Assigning the base to be 7,

I hope I was able to answer your question. Have a good day.
Answer:
t(99)= -2.89
Step-by-step explanation:
-To places after the decimal point is equivalent to rounding off to the nearest hundredth.
-To round off to the nearest hundredth, we check the thousandths digit:
- If the thousandths digit is less than5, we round down to the previous hundredth.
- If the thousandths digit is greater than 4, we round up to the next hundredth:
Hence,
