Let A be an m times n matrix. Explain why the equation Upper A Bold x equals Bold b has a solution for all b in set of real numbers R Superscript m if and only if the equation Upper A Superscript Upper T Baseline Bold x equals Bold 0 has only the trivial solution.

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.

step-by-step explanation:

hope my answer has you!

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

i believe it's a.

i'm not sure on this one, most likely correct.
