Answer:
reflection over the x-axis
shifted 3 right
shifted 2 up
Step-by-step explanation:
This function is quadratic. Quadratic graphs are written as y=a(x-h)^2+k. Where a is a non-zero number that affects the vertical appearance of the graph, h is the horizontal placement, and k is the vertical placement.
When a is negative then, the graph has been reflected over the x-axis. This makes it look like it has been turned upside down. The variable h affects how the x-values are shifted. In this equation, h looks negative but it is actually positive because if you look at the formula, h is being subtracted. Positive h values move the graph right. So, the graph is shifted 3 units to the right. Finally, k does the same thing as h but on the vertical (y) axis. So, +2 makes the graph shift 2 units up.
Answer:
No.
Step-by-step explanation:
If it is geometric the quotient of the terms and the previous term will be a constant.
213 / 31 = 6.871
4459 / 213= 20.93
These are not equal so the sequence is not geometric.
Um, it should just be n + 1 because then it would be the next integer.
Step-by-step explanation:
Given
c² = a² + b²
Making a² subject then
a² = c² - b²
Hope it will help :)
Answer:
Step-by-step explanation:
Let d= dramas
c= comedies
r= reality shows
Dramas are 1 hour long, comedies are 30 minutes, and reality shows are 2 hours long.
Total time spent on watching = 
[ 
]
Since he spent 8 hours for this, that means
→ First equation
He watches twice as many comedies as dramas.
i.e. 
→ second equation
So, the system of equations could be used to determine how many of each type of show he watches each week:
