Answer:
A system has infinitely many solutions when it is consistent and the number of variables is more than the number of nonzero rows in the rref of the matrix. For example if the rref is ��has solution set (4-3z, 5+2z, z) where z can be any real number.
The answers are C and E,
According to the interior and exterior angle theorem, this should be correct:
<3+<4+<6=180
<3+<1=180
<4+<6=<1
so they are the interior opposite of <1
A. Its a square. This means each side times the side would give us the area (s^2)
4/3^2 or 1.3333 x 1.33333 = 16 / 9 area.
B. Really just pick any numbers you want.
16 yards long and 1/9 wide.
As long as they multiply to 16/9
Answer:
-5.1x + 12.3
Step-by-step explanation:
Combine like terms: first, combine the x terms, obtaining -5.1x.
Next, combine the constants, obtaining 12.3.
The simplified expression is -5.1x + 12.3
