What does x equal? Please help

Mathematics
1 answer:
Norma-Jean [14]3 years ago
8 0

Answer:

x=-9

Step-by-step explanation:

9^{2x-3}=27^{2x+4}\\(3^2)^{2x-3}=(3^3)^{2x+4}\\3^{2(2x-3)}=3^{3(2x+4)}\\3^{4x-6}=3^{6x+12}

As the bases(3) are same,

we can conclude that the powers are equal.

Hence,

4x-6=6x+12\\-6-12=6x-4x\\-18=2x\\x=-18/2\\x=-9

Help help help help meeeeee
Pavel [41]

Answer: T (The first option).


Step-by-step explanation:

1. By definition, coplanar points are three or more points that are in the same plane.

2. Based on this information, as you can see in the figure attached, the points A, C, D, E, S and U are coplanars because they are in the same plane, which is: ACDE.

3. Therefore, you can conclude that the point T is not coplanar with points A, C and D because this is not in the plane ACDE.
