Answer:
x= -2
Step-by-step explanation:
64^x = 16^x-1
64= 4^3 and 16=4^2
4^3x = 4^2(x-1)
so we now cancel the 4 from both sides and equate the powers
3x=2(x-1)
3x=2x-2
we now put all the x on one side
3x-2x=-2
x= -2
A convenience sample is made up of people who are easy to reach so it would be B
X - y = 28 (difference between the two numbers)
and
x - 8 = 2y (8 less than twice the smaller number)
From the first . . . x = 28 + y
28 + y - 8 = 2y
20 = 2y - y
20 = y
x - 20 = 28
x = 28 + 20 = 48
Answer:
