Answer:
The third option, x < -2 or x ≥ 4
Step-by-step explanation:
First, we need to interpret the graph.
There is an open circle at -2 and a closed circle at 4, which means that x does not include 2 and includes 4.
The left arrow points to numbers lower than -2, and the right arrow points to numbers greater than 4, so X is less than -2 and greater than 4.
Answer: For 10 sessions, the cost of the two plans the same.
Step-by-step explanation:
Let x= Number of sessions.
Given: Christian’s Gym charges a one-time fee of $50 plus $30 per session for a personal trainer.
Total charge for x sessions = 50+30x
Nicole's fitness center charges a yearly fee of $250 plus $10 for each session with a trainer.
Total charge for x sessions = 250+10x
When both plan charges the same, then
![50+30x=250+10x\\\\\Rightarrow\ 30x-10x=250-50\\\\\Rightarrow\ 20x=200\\\\\Rightarrow\ x=10](https://tex.z-dn.net/?f=50%2B30x%3D250%2B10x%5C%5C%5C%5C%5CRightarrow%5C%2030x-10x%3D250-50%5C%5C%5C%5C%5CRightarrow%5C%2020x%3D200%5C%5C%5C%5C%5CRightarrow%5C%20x%3D10)
i.e. For 10 sessions, the cost of the two plans the same.
Answer: no, it does not mean the same thing
