Answer:
x ≥ -5
Step-by-step explanation:
If we have a translation to left c units, we write " x + c " in the function, and
If we have a translation to right c units, we write " x - c" in the function
If we have vertical translation up b units, we "add b to the function", and
If we have vertical translation down b units, we "subtract b to the function"
The parent function is 
Since translation left 5 units and up 3 units, we can write:

The domain is affected by the square root sign and we know the number under the square root CANNOT be negative, so we can say:
x + 5 ≥ 0
x ≥ -5
This is the domain.
Answer:
24
Step-by-step explanation:
30% of the pie chart is pizza. 30% of 80 = 0.3 * 80 = 24
Answer: I believe the last answer is the correct one. adj/opp
change,c = 20 - p
so in Excel for example
put 20 in column a
put 11.59, 17.50 etc in column b
in column c put the equation '=20 - b1'
