Answer:
0
Step-by-step explanation:
adding -7 to 7, since they are both constants (no variable) gives you 0. Adding -5x and 5x since they both have an x term gives you 0x also written as 0 (0*any number is 0). this gives you a final answer of 0
-7 and 7 cancel out, and 5x and -5x cancel out too.
0+0=0
-3(2x+1) > -2(x+6)
-6x -3 > -2x - 12
-6x -3+6x > -2x - 12+6x
-3>4x-12
-3+12>4x-12+12
9 > 4x
4x<9
x<4/9
(-∞, 4/9)
D 1 and -1
divided by 8
(x+1)(x+1)=0
so x=+-1
D
using the rule of logarithms
log x - log y ⇔ log ( )
then
( ) = a - d
