Answer:
x≤4
Alternate form
x∈(-∞,4]
It's the third
Step-by-step explanation:
x-5≤-1
Move the constant to the right-hand side and change its sign
x≤-1+5
calculate the sum
x≤4
Alternate form
x∈(-∞,4]

Step-by-step explanation:
subtract 8.75 and 6.25 to get the cost of 1 pizza slice since Alfredo bought 1 more pizza than Jessica.
The given equation represents a function and inverse of the function exist if x ≥ 6.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
y = 2(x – 5)² – 6
Part A:
Using vertical line test, we can find the whether the graph is a function or not.
After drawing a graph for the given curve, and drawing a vertical line.
The vertical line touches only one point for the one input.
The given equation represents a function.
Part B:
Replace x → y and y → x
x = 2(y – 5)² – 6
2(y – 5)² = x + 6
Plug x = 1 in the y:
y = 26
Plug 
= 1 in inverse of a function:
x = 26
Thus, the given equation represents a function and inverse of the function exist if x ≥ 6.

Answer:
A = 5
B = 9
Step-by-step explanation:
This was very simple!
Nancy needs at least 15 boxes of travoprost but she only has 10. To find out how many she needs, we subtract 15 from 10 to get 5 boxes
Nancy also needs at least 12 boxes of latanoprost but she only has 3. To find out how many she needs, we subtract 12 from 3 to get 9 boxes
Therefore A = 5 boxes; B = 9 boxes
