2^(2x-1)-9 X 2^(x-2)+1=0
capital X is multiply sign please help​

x is undefined

Step-by-step explanation:

Given the equation

2^(2x-1)-9 X 2^(x-2)+1=0

Recall that

a^x * a^y = a^x+y

Hence

2^(2x-1)-9 X 2^(x-2)+1=0

2^(2x-1)-9 + (x-2)+1 = 0

2^2x - 1 -9 + x -2 + 1 = 0

x is undefined

step-by-step explanation:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
