Answer:
The function y= sec(x-2)+2 is shifted two units to the right and 2 units upwards., compared to y=sex(x).
Step-by-step explanation:
To solve this problem we need to know the rules for translation of graphs:
Given the function y = f(x):
- y=f(x-a) is the same graph shifted 'a' units to the right. If 'a' is negative, then, the graph is shifted to the left.
- y = f(x) - a is the same graph, but shifted 'a' units downwards. If 'a' is negative, then the graph will be shifted upwards.
In this case, our main function is y=sec(x). And the function y= sec(x-2)+2 is shifted two units to the right and 2 units upwards.

Steps:
If you do the steps correctly, the answer should be 44 ice cream scoops.
(Short way to do this problem/question)
Information given:
1. He uses 1/16 of the bottle of syrup(Every scoop of icecream he eats)
2. The question wants us to find, if he had ate 2 3/4 bottle of chocolate syrup.. how many scoops did he eat.
The steps are::::
1/16 = 16 (scoops of icecream)
Now, if we do 16 times 2 3/4 we would get...
44.
Hence, the answer is 44 scoops of icecream.
Answer:
1394
Step-by-step explanation:
Set up equation to find the number:
Variable n = number
65/100 = 1105/n
Cross multiply:
65 × n = 100 × 1105
65n = 110,500
n = 1700
Check your work:
1700 × 65%
Convert percentage into decimal:
1700 × 0.65
1105
Correct!
Find 82% of 1700:
Variable x = 82% of 1700
82/100 = x/1700
82 × 1700 = 100 × x
139,400 = 100x
1394 = x
Check your work:
1700 × 82%
1700 × 0.82
1394
Correct!
