Domain is everything below 0. Range is all real numbers. It is a function as it passes the vertical line test.
Answer:
a = 30/5 = 6
Step-by-step explanation:
Answer: 10x-30=90 I think 10x=90-30, 10x=60, x=60/10, x=6
Step-by-step explanation:
Answer: Because of gaps between the vertex of Pentagons and hexagon.
Step-by-step explanation:
The Pentagon has 5 sides and 5 vertex angles. While hexagon has 6 sides and six vertex angles
The sum of the angle of polygon is equal to ( n - 2 )180
Sum of the angle of a Pentagon will be: (5 - 2)×180 = 540
Each vertex angle of a Pentagon = 540/5 = 108
Sum of the angle of hexagon will be: (6 - 2)×180 = 720
Each vertex angle of a hexagon =
720/6 = 120
To interlock Pentagon and hexagon, the sum of the combination of vertex angles of both must be equal to 360 ( sum of the angles at a point = 360)
Since there is no number of combinations that can be equal to 360, there will surely be a gap.
Answer: 
Step-by-step explanation:
You know that Mr. Wilson uses the following equation to find the cost:

Then, if Mr. Wilson spent $30, you can follow these steps in order to calculate how many hours he parked in the parking garage:
1. You need to substitute
into the given equation:

2. Now, you must solve for "H":

Therefore, based on the result, you can conclude that Mr. Wilson parked his car in the parking garage for 8 hours.
