HELP. It’s LOG form. Since were out of school I forgot how I did this and it’s due so it would be a life saver.
____ [38]

Answer:

see below

Step-by-step explanation:

exponent to log: a^b = c ---> logₐc = b

ie. question 6

log ₁₀(3x+1) = 2 -----> 10^{2} = 3x+1

that will get you through questions 1 to 3, 5 to 6, and 8

in question 4, all you have to do is know that 2^2 = 4 and 2^3 = 8, by setting the bases equal, you can manipulate the exponents to get 2x+8 = 3x-3

for questions 7 and 9,

remember that:

logₐc + logₐd = logₐ(cd)

logₐc - logₐd = logₐ(\frac{c}{d})

remember change of base is log_{a} b = \frac{log_xb}{log_xa}, this will be useful if you need your calculator since calculators only have base 10 and maybe if your calculator is good enough natural base e

What’s the equation to convert 100 inches per minute to feet per hour
laiz [17]
Let's look at each part of the equation. We need to first convert the inches to feet then multiply it by 60 to get per hour.
To convert inches to feet, we need to divide by 12.
100÷12
8 1/3
We need to then multiply it by 60 to find per hour.
8 1/3×60= 500
Let's put the equation together, we'll need parenthesis.
( \frac{100}{12} )*60=500
