You are an electrical engineer designing a new integrated circuit involving potentially millions of components. How would you use graph theory to organize how many layers your chip must have to... more

Please, help me to solve for x. Show steps.  Thank you! 

Use process of optimization

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 R3. Is there a way to... more

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 if it is in the range or... more

My answer would be because it involves only addition, subtractions and multiplications, no divisions. But I am not 100%sure. 

. 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... more
