Answer:
B) H
Step-by-step explanation:
Notice that a regular hexagon has a <em>six-fold rotational symmetr</em>y.
Every time you rotate it about its centre by one-sixth of a circle (60°), you map a vertex onto the one next to it.
If you rotate the hexagon 300° counterclockwise, that is equivalent to rotating it 60° clockwise.
When you rotate the hexagon 60° clockwise (one-sixth of a circle),
Point N maps onto point H.
(5x-1)(x+2)=8x-4
5x²+10x-x-2=8x-4
5x²+9x-2=8x-4
5x²+x+2=0
use the quadratic formula, b²-4ac=1²-4*5*2=1-40=-39, -39 cannot be square rooted, so the equation has no real solution.
Answer:
-log2
Step-by-step explanation:
log4 - log8 = log2² - log2³
= 2log2 - 3log2
= (2 - 3)×log2
= (-1)×log(2)
= -log2
