Answer :
<em>( 6 y^4 + 3 y^2 -7) - (12 y^4 - y^2 + 5)</em>
Step-by-step explanation:
(6 y^4+ 3 y^2-7) - (12 y^4 - y^2 + 5 )
=6 y^4 +3 y ^2 - 7 - 12 y^4 + y^2 - 5
=6 y ^4 - 12 y ^4 +3 y ^2 + y ^2 - 7 -5
= -6 y ^4 + 4 y ^2- 12

Answer:
Equation: y=1.5x+4 Will total $10 after 4 hours
Step-by-step explanation:
Format: y=mx+b
y is total cost
m is per hour
b is starting cost
Equation: y=1.5x+4
After 4 hours, it will be $10 because:
10=1.5x+4
subtract 4 both sides
6=1.5x
divide 6 by 1.5
4=x
Hence the 4 hours answer
Both should be yes..there is exactly one x input for every y input
6^3= 6x6x6=216. I hope this helps!
