Trenton said that 9 to the power of three times 9 to the power of eight ( eight is negative) = nine to the power of 5 (5 is negative). kendal said 9 to the power of three times 9 to the power of 8(8is negative) = 1/9 to the power of 5.determine who is correct .justify your answer

my guy how are we supposed to know

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4
