Answer:
- 25 seats per row in 18 rows
- 30 seats per row in 15 rows
Step-by-step explanation:
The total number of seats is 470 -20 = 450.
The number of seats in a row is found by dividing seats by rows.
<u>In 18 rows</u>
450 seats/(18 rows) = 25 seats/row
<u>In 15 rows</u>
450 seats/(15 rows) = 30 seats/row
Hello there!
You have to do PEMDAS to solve this problem
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
We're doing: addition, parentheses , and multiplication!
So, 8(2) = 16, right?
Problem becomes: 4 + (16) - 3 + 5
4 + 16 = 20
Problem becomes: 20 - 3 + 5
20 - 3 = 17
17 + 5 = 22
So, therefore your answer would be: 22
Good luck on your assignment and enjoy your day!

Answer:
The answer is reflection on the y-axis
Step-by-step explanation:
Reflection on the x-axis will change the y-intercept
Horizontal shrink will change the slope but not to the point of making the 3 negative
Horizontal stretch is the same concept
Thus Reflection on the y-axis on the y-axisis the answer
Hope this helps!

thus f[ g(x) ] = x indeed, or g[ f(x) ] =x, thus they're indeed inverse of each other
