Answer:

A) True

Step-by-step explanation:

A basic variable is a variable that corresponds to a pivot column. A variable that does not corresponds to a pivot column is known as a free variable. It is required to row reduce the augmented matrix into echelon form so as to determine which of the variables are free and which of them are basic.

1. Find the value of x in the equation √ x + 5 = √ x + 45.<br> A. 16<br> B. 4<br> C. 1<br> D. 2
Korvikt [17]
I think you mean
sqrt x + 5 = sqrt (x+45)


if you plug in x = 4,
left side = sqrt 4 + 5 = 2+ 5 = 7

right side = sqrt (4+45) = sqrt 49 = 7

so the answer is x = 4 :)
