Answer:
(xy - 4)(xy + 4).
Step-by-step explanation:
The is the difference of 2 squares.
a^2 - b^2 = (a - b)(a + b: so we have:
x^2y^2 - 16 = (xy - 4)(xy + 4)
Sorry don’t now the answer to this problem
Answer:
c
Step-by-step explanation:
From the definition of a function, an x-value cannot have more than 1 corresponding y-value. Since x = -5 has already been used, it cannot be used again with a different value for y.
Answer:
To determine the inverse of the given function, change f(x) to y, switch x and y and solve for y and f^-1(x)= ln(x+4)/2
Step-by-step explanation:
f(x) = e^2x - 4
to find the inverse let
y = e^2x - 4
Replace x and y
x = e^2y - 4
and now, solve to find value of y
x + 4 = e^2y
taking ln on both sides:
ln(x+4) = ln(e^2y)
ln(x+4) = 2y
=> y = ln(x+4)/2
=> f^-1(x)= ln(x+4)/2
So, To determine the inverse of the given function, change f(x) to y, switch x and y and solve for y and f^-1(x)= ln(x+4)/2
Answer:
hello
we can think like the hamburger is all equal to 100.
if the first bite was %20 of the hamburger, we can say there left 80. because 100×20/100 its = 20 and 100-20= 80. the problem is not this i wanna say. there was a teory similar like this problem.
a girl was going to her home. in every step she was going 2/1 of the road.. it was impossible to arrive to home.
we said 100 for all hamburger right?
it would be 0,0000000100 too..
so if we continued to dividing by %20 everytime, we never had a result of it.
maybe at least we found 0,0000000000001.
And? then we had to found 0,0000000000001's %20.
soo, the problem's answer is its not possible.
good luck(: (sry for nub eng)
