We have to identify the statement about the plane which is not true.
1. Consider the first statement,
" A plane can be thought of as flat". It is true as plane is a flat surface.
2. Consider the second statement,
"The surface of a plane is made up of points". It is true as plane is a flat surface which is made up of points.
3. Consider the third statement,
"A plane can be seen". It is not true as plane is a flat surface which can not be seen.
4. Consider the fourth statement,
"A plane extends infinitely in all directions". It is true as plane is a flat surface that extends infinitely along its edges.
Answer:
In 4 months the cost of both gyms will be the same.
Step-by-step explanation:
At first we need to model the function to calculate the cost of the 2 gyms.
Slope-intercept equation of linear function
where
slope of line
y-intercept
Let linear function to calculate total cost of gym be:
where
total cost of gym
cost per month (slope)
number of months
start-up fee (y-intercept)
For Gym 1
, 
For Gym 2
, 
In order to find the number of months the cost of both gyms will be the same, we need to equate both functions and solve for number of months 
So,
In 4 months the cost of both gyms will be the same.
Answer: A. 3 ways: k, DE, ED (both DE and ED have line markers over top)
To name a line, we just need two points on the line. We list them in any order because the line extends forever in both directions. Contrast this with a ray where order does matter. The little k is another way to name a line, potentially simplifying things.
Choice B is close, but it mentions ray DE instead of line DE. Choice C is missing line ED. Choice D is a similar story as choice B. These facts allow us to rule out B through D.
