Answer: (-infinity, 7]</h3>
=====================================
Explanation:
The first interval (-infinity, 3) describes any number less than 3, so we can write x < 3 in short hand (where x is the unknown number).
The second interval (-1, 7] means we start at -1 and stop at 7. We do not include -1 but include 7. So we say that 
(ie x is between -1 and 7; exclude -1, include 7)
If you were to graph each ona number line, you would see that the too intervals have overlapping parts. The right most edge extends out as far as x = 7. There is no left most edge as it goes onforever that direction.
Therefore, the to intervals combine to get 
which turns into the interval notation answer of (-infinity, 7]
-----------
It might help to think of it like this: x < 3 and say "x is some number that is less than 3, or it is between -1 and 7". So x could be anything less than 7, including 7 itself.
I don’t quite understand this question since it’s all spaced out and there’s no picture but since domain is x/the indecent variable, “x = -6, -1, 0, 3” (the first answer choice” is correct
Answer:
Step-by-step explanation:
(3x^2-4x+10)(x^3+5x-20) =
x=1 is not a good value since when you plug it in you get -126 and you can't have a negative number of seeds.
Answer:
5 3/7
Step-by-step explanation:
On this one all you basically have to do is 4+1 since they are both whole numbers, then attatch the fraction onto that.
4+1=5
5 3/7
B
Step-by-step explanation:
2000$ is far from 30$ so it is b
