What conditions on a matrix A ensure that Ax=b has a solution for all b in Rn? Select the best statement. (The best condition should work with any positive integer n.) A. The equation will have a solution for all b in Rn as long as the columns of A span Rn. B. The equation will have a solution for all b in Rn as long as the columns of A do not include the zero column. C. The equation will have a solution for all b in Rn as long as no column of A is a scalar multiple of another column. D. There is no easy test to determine if the equation will have a solution for all b in Rn. E. none of the above

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

i believe it is b and c. (side note, i got the same computer from k-12 lol i’m in 8th grade and this is my first year, will it get

step-by-step explanation:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
