Step-by-step explanation:
it means that x has now to be the result variable, and y the input variable.
so,
y = 3x - 5
y + 5 = 3x
x = (y + 5)/3
and as a final touch, to make the inverse a "normal function", we rename x to y and y to x and get
y = (x + 5)/3
as the inverse function
Always
a=b
subtract c from each side
a-c = b-c
I’m not rlly sure if i did it right & i’m sorry if i didn’t. i used the FOIL method
f= first to first
o=outer to outer
i=inner to inner
l= last to last
so it’d be
8b + 6b = 14b (f)
8b+ 8=16b(o)
-7+6b=-1b(i)
-7+8(l)
and then you add like terms so
[14b+16b-1b]+1
= 29b+1
Answer:
r≈5.36656314
Step-by-step explanation:
Since A=πr(r+
) so we get that 226.08/pi≈72 or 226.08/3.14=72 we then plug it in to get 72=r(r+
) so we get r≈5.36656314
