This question wants to know the domain. For example: (2,4) 2 is the domain and 4 is the range.
Then, they want you to solve by finding X the range when x =-1
x-4/x^2+5x-36
Put -1 everytime you see x
-1-4/-1^2+5(-1)-36
-5/1+(-6)-36
-5/-41 This is the range.
Answer: 10/3
Step-by-step explanation
2/3x5
2/3x5/1
Now goahead and multiply the top and bottom numbers
Usually you use addition to find a sum.
Answer: the system of equations are
0.1x + 0.04y = 162
y = 2x
Step-by-step explanation:
Let x represent the total dollar amount of the phone sales she makes.
Let y represent the total dollar amount of the computer sales she makes.
Charlotte earns a 10% commission on the total dollar amount of all phone sales she makes, and earns a 4% commission on all computer sales. If she earned a total of $162 in commission, it means that
0.1x + 0.04y = 162
Charlotte had twice as much in computer sales as she had in phone sales. This means that
y = 2x
