Answer:
-1
Step-by-step explanation:
putting x=-3 in the function
-2(-3)-7
6-7
-1
Plug in (1,8) to y ≤ 2x+2 and you get 8 ≤ 2+2 which is not true
Applying the segment addition postulate, SU = 10
<h3>What is the Segment Addition Postulate?</h3>
Based on the segment addition postulate, when a point lies in between two endpoints on a line segment, the sum of the lengths of the two smaller segments equals the length of the longer segment.
Given:
SU = 2x - 12
TU = 6
ST = x - 7
Thus:
TU + ST = SU
6 + x - 7 = 2x - 12
-1 + x = 2x - 12
-2x + x = 1 - 12
-x = -11
x = 11
SU = 6 + x - 7
SU = 6 + 11 - 7
SU = 10

<span>The regular hexagon ABCDEF rotates 240º counterclockwise about its center to form hexagon A′B′C′D′E′F′. Point C′ of the image coincides with point _E_ of the preimage. Point D′ of the image coincides with point _F_ of the preimage.</span>
It should be just 12b, since they all have the same exponent, they can all be combined.
