Let ax=b be any consistent system of linear equations, and let xj be a fixed solution. prove that every solution to the system can be written in the form x= x1 + xo, where xo is a solution to ax= 0. prove also that every matrix of this form is a solution.

7

step-by-step explanation:

the answer would be 7

b

step-by-step explanation:

write an equation for the line of best fit. then predict the number of milk cow operations in the year 2005.

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.
