Well this is easy.
We have linear inequality,
Simplifying this a bit to get,
Divide by 3 (both sides),
Or with interval notation, 
.
Hope this helps. :)
Umm what? I don’t think i can answer this cause i can barely read it.
Answer:
For the first one, put the input(0) in the place of x. This would make it look like this, 3x0+5
The x is a times sign, which was added when you add the number.
The rest goes like this,
3x0=0
0+5=5
Ouput= 5
By calculator: it's 2.378
Since 2^5 = 32, so 32^(1/4) = 2^(5/4)
31. +
34. -
To figure out more, just solve the known problem, and then go over what the answer would be to the unknown one until you find the answer that makes it true.
