You can say there are 3 groups and 6 people are in it how many people are they? which the answer is 18.
Answer:
x1 = -1, x2 = 2, x3 = -4, x4 = 0
If it wants everything in terms of what x4 equals then the system is inconsistent since x4=0
Step-by-step explanation:
Once you have it in that reduced row echelon form it's super easy.
The first column is x1, second is x2 and so on.
The first row says x1 + 0x2 + 0x3 + 0x4 = -1, or in other words x1 = -1. You can do this for all the rows.
this does mean that x4 = 0, so if the instructions are saying it wants everything n terms of x4, you can't do that so it is inconsistent.
okay so basically its an increase of 3.5% of 25 dollars and 67 cents.
So
basically
(25.67)* .035 -----> To get .035, you will need to move the decimal to the left twice to make it into a decimal to get the percentage of the total amount.
So the total of that amount would be
89 cents ( ignore numbers after 9 because your just looking at the 2 first number after you did your equation).
Then you add the total amount ( The amount for the meal) + The TAX
So you will get 25.67 + 89 = 26.56
If you got any more questions of what I said ( because it's confusing). Tell me!
ANSWER: $26.56
Answer:
Odd
Step-by-step explanation:
Looking at f(x)=x-3x^3, we see that all powers of x are odd: x^1 and x^3.
Thus, this function is ODD.
