Answer:
1. -6y^4 +4y^2 -12
2. x - 19
Step-by-step explanation:
1.
(6y^4+3y^2-7) - (12y^4-y^2+5)
= -6y^4+ 4y^2- 12
2. 3(x-5) - (3x+4)
= (3x-15) - (3x+4)
= x-19
Answer:
f^-1(x)=1/2x+5
Step-by-step explanation:
y=2x-10
inteechange 'y' with 'x'
x=2y-10
make 'y' the subject
2y=x+10
divide by 2both sides
y=(x+10)÷2
y=1/2x+5
f^-1(x)=1/2x+5
