For this case we have the following inequality:
![\frac{x-9}{7x+2} \leq 0](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx-9%7D%7B7x%2B2%7D%20%20%5Cleq%200)
Solving for the numerator we have:
![x \leq 9](https://tex.z-dn.net/?f=x%20%20%5Cleq%209)
Solving for the denominator we have:
![x \ \textgreater \ \frac{-2}{7}](https://tex.z-dn.net/?f=x%20%5C%20%5Ctextgreater%20%5C%20%20%20%5Cfrac%7B-2%7D%7B7%7D%20)
Therefore, the solution is given by:
![\frac{-2}{7} \ \textless \ x \leq 9](https://tex.z-dn.net/?f=%20%5Cfrac%7B-2%7D%7B7%7D%20%5C%20%5Ctextless%20%5C%20%20x%20%20%5Cleq%209%20)
The graph that shows this solution is the graphic number 3.
Answer:
option 3
Answer:
Yes. Every unique input has a unique output.
Step-by-step explanation:
Since every input has a different output, therefore it's a function. It's not a function when the input have more than 1 output. When graphing, make sure you take the vertical line test to see whether or not the graph is a function.
Answer:
y=54/7
Step-by-step explanation:
The first one
Running forward is adding
Running opposite direction is subtracting
5-5
5-6
6-5
6-0
5-5 is the only one that equals 0
Step-by-step explanation:
by considering how many inches (") are in one foot (').
the answer is 12. there are 12 in in every ft.
so, now we can convert everything to the smallest scale (inches) and do the calculation based on inches :
(8×12 + 4) - (2×12 + 6) = 96 + 4 - 24 - 6 = 100 - 30 = 70"
and now to translate 70" back into ft and in :
70/12 = 5 with a remainder of 10
70" = 5' 10"
