For this equation you would need to combine like terms
Step 1: -2+1= -1
Step 2: -4i+6i= 2i
so your answer to this question would be -1+2i
it is gonna be c trust me I know for a fact
The price of chips is $ 0.75, the price of a hot dog is $ 2 and the price of a soft drink is $ 1.25.
Step-by-step explanation:
Given,
A customer buys 4 hot dogs, 3 bags of potato chips, and 4 soft drinks for $15.25.
The price of a hot dog is $1.25 more than the price of a bag of potato chips.
The cost of a soft drink is $2.75 less than the price of two hot dogs.
To find the cost of each item.
Let,
The price of chips = x
The price of a hot dog = x+1.25
Price of two hot dog = 2(x+1.25) = 2x+2.5
The price of a soft drink = 2x+2.5-2.75 = 2x-0.25
Now,
According to the problem,
4(x+1.25)+3x+4(2x-0.25) = 15.25
or, 15x+5-1 = 15.25
or, 15x = 11.25
or, x = 0.75
Hence,
The price of chips = $ 0.75
The price of a hot dog = $ 0.75+1.25 = $ 2
The price of a soft drink = $ 2×0.75-0.25 = $ 1.25

Answer: The mode is: 3 . The range is: 6 .
___________________________________
Explanation:
___________________________________
It would be best to list this values in the data set given, from least to greatest:
________________________________________________
{ 3, 3, 3, 3, 4, 5, 5, 6, 9 } .
________________________________________________
The mode is the number that occurs most frequently in the data set, which is: "3".
_________________________________________________________
{The number, "3", occurs FOUR (4) times. The number, "4", occurs ONE (1) time. The number, "5", occurs TWO (2) times. The number, "6", occurs ONE (1) time. The number, "9", occurs ONE (1) time.}.
___________________________________________________
The range is calculated from subtracting the LOWEST value in the data set FROM the HIGHEST value in the data set.
____________________________________________________
The lowest values in the data set is: "3" .
The highest value in the data set is: "9" .
________________________________________________
To calculate the range: 9 <span>− 3 = 6 . The range is: "6".
