The line including (3, 1)and (-2, 3).
Consider the sum: (5)2 + (11)2 + (17)2 + ... + (18n - 1)2 How do I write this in sigma notation? The final term is really confusing me.
True or False?

I'm trying to understand matching functions to their graphs. I've been given pictures of graphs and four functions. I am suppose to match each function to the correct graph.
Show that the set V of all 2x2 upper triangular matrices is asubspace of M22 I need to turn this in tonight by 12 pm. Please, help!
w1=5x1-x2+x3 w2= -x1+x2+7x3 w3= 2x1-4x2-x3 My solution so far: From the system I can tell that it is R3, so domain is R3, since there w1, w2, w3 I can tell that codomain is...
T:R3 - R3: T (x,y,z) = (2x-y, x+z, y-z); w= (3,3,0) Here is my solution: T (3,3,0) = (2x3-3, 3+0, 3-0) T (3,3,0) = (3, 3, 3) What I am doing wrong? And how to explain...
My answer would be because it involves only addition, subtractions and multiplications, no divisions. But I am not 100%sure.
a sraight line is a line that has a one end point and a arrow that keeps going the other direction
. Indicate whether the statement is true or false. Justify your answer. (a) If Ax=b has infinitely many solutions, then so does Ax=0 (b) If Ax=b is inconsistent, then Ax=0 has only the trivial...
