Answer:
g(f(x)) = 8x-18
Step-by-step explanation:
Given that,
f(x) = 5 - 2x
g(x) = -4x + 2
We need to find g(f(x))
.
g(f(x)) = g(5-2x)
= -4(5-2x)+2
= (-4) (5) +(-4)(-2x) +2
= -20 +8x +2
= 8x-18
Hence, the value of g(f(x)) is 8x-18
200000J/200KJ
Step-by-step explanation:
using k.e=1/2(mv2)
k.e=1×1000×20²/2
k.e=400000/2
k.e=200000J/200KJ
Write the equation as such and narrow down x value being 4
Answer:
4^5/4^2
Step-by-step explanation:
We know 1/a^b = a^-b
a^b/ a^c = a^(b-c)
1/4^3 = 4^-3
4^2/4^5 = 4^(2-5) = = 4^-3
4^5/4^2 = 4^(5-2) = 4^3
4^-3
