Homework Help: Algebra 2

Posted by mysterychicken on Sunday, May 1, 2011 at 4:37pm.

Is it me or does this problem not make sense? (you can't solve it)

5. Solve for x in the following system:
6x + 6y = -2
y = -x

I also need help in these:

38. We can take the product AB only if the number of columns of A equals the number of rows of B. -True?

40. The graph of the following system yields perpendicular lines:

x + 2y = -10
-4y = 2x + 20

True or False?

42. If we multiply a 2 x 2 matrix with a 2 x 1 matrix, the product is a 2 x 1 matrix.
-False?

Thanks
