Answer – Always
A negative number raised to an odd power is always negative. When a negative number is raised to an even power, the pairs of negatives will cancel out; but when it is raised to an odd power, after pairs of the negative sign have canceled each other out, there will still be one minus sign left unpaired, which will not cancel out.

Answer:
2x+12
Step-by-step explanation:
add the 7 and the 5, you don't need to answer the equation you just need to shorten the equation.
The question requires us to add the two functions.
F(x)=8−4x−x³
g(x)=x²<span>+7x−9
</span>F(x)+g(x) = (8−4x−x³)+(x²+7x−9)
=8-9+7x-4x+x²-x³
= -1+3x+x²-x³
=x²-x³+3x-1
Answer:
let the price of a glass of milk be m and the price of seafood dinners to be s
A. for the first equation , we can see that
3m+5s =38.5 ........1
and second equation
m+2s= 15.15........2
B. 3m+5s= 38.5 ......1
m+2s=15.15 .......2
using substitution method
make m subject in eqn 2
m= 15.15 - 2s
put m in eqn 1
3(15.15-2s) +5s=38.5
45.45 -6s+5s =38.5
-6s +5s =38.5 -45.45
-s= -6.95
divide both sides by -1
s = $ 6.95
m= 15.15 -2s
m= 15.15- 2(6.95)
m= 15.15 -13.9
m=$ 1.25
therefore the price of a glass of milk is $1.25 and the price of a seafood dinner is $6.95
8/25 is the answer. Hope this helps.
