Consider the following linear systemx1 + 2x2 ∈ x3 + 5x4 = 12x1 + 2x2 ∈ 2x3 + 6x4 = 3x1 + x2 ∈ x3 + 3x4 = 2(a) Row reduce the augmented matrix to the reduced row echelon form.(b) Determine if the linear system is consistent or inconsistent. (If the systemis consistent, you do not need to find the general solution.)

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

its adding 5.5 each time
