Answer:
2(n-8) = 5
Step-by-step explanation:
I'm assuming that its supposed to say "a number <em>and</em> 8"
Answer:
5.414
subtract 8.13 from 2.716 and u will get ur answer
1)421x=6
x=70
2)x+6(6x)=420
x+36x=420
37x=420
x=11
3)x-6x=420
5x=420
x=84
4)x+6x=420
7x=420
x=60
Answer:
(g°f)x =16 when x = 5
Step-by-step explanation:
It might be easier to understand if you wrote this the other acceptable way.
g(x) = x^4
f(x) = 2x - 8
g(f(x)) means that in g(x) wherever you see and x you put f(x)
g(f(x)) = (f(x) ) ^ 4 Now put in the general value for f(x)
g(2x - 8) = (2x - 8)^4
You really don't want to expand this (although it would give you the right answer eventually).
g(2*5 - 8) = (2 * 5 - 8)^4
g(2*5 - 8) = (10 - 8)^4
g(2*5 - 8) = 2^4
Answer 16
Answer:
y = -x/3 + 5/3
Step-by-step explanation:
In order to find the inverse of a function, you have to switch the x and y values, and then solve for y again.
f(x)=-3x+5
y = -3x + 5
x = -3y + 5
x + 3y = 5
3y = 5 - x
3y = -x + 5
y = -x/3 + 5/3
