The phrase “inequality” tells you that you will be using inequality signs, greater than, less than, greater than or equal to, or less than or equal to. Those signs look like this (not ordered) ≤ ≥ < >
So now we have to consider the speed limit 25mph, and remember s is used to represent how fast you are going. We can start be setting up 25_s and now we must determine what sign to use. Does it make sense to go faster than the speed limit? No it doesn’t, it’s a limit. what about equal to, does it make sense to go at the speed limit? Yes you can travel 25mph in a 25mph zone. So your speed will be less than or equal to 25, because you know you can’t go faster than that but you can travel at that number. So it looks like:
25 ≥ s.
If you need help understanding why I used that particular inequality sign message me for help.
That equation is an upward-opening parabola so the domain is (- ∞, ∞)
Answer:
x=1 and x=-4
Step-by-step explanation:
Put it into your calculator, go to graph and look at which points it says ERROR.
What is your question? Type it and i will gladly help! :D
Because you are 12 you put down
12
x can be anything so if you write
12x
You can later substitute it for 3. 12(3)
Your uncle is 2 years more
12x+2 is your equation
or
12(3) + 2
