Answer:-1/2
Step-by-step explanation:
16^x=1/4
(4^2)^x=4^(-1)
4^2x=4^(-1)
Base cancelled each other since they are the same
2x=-1
Divide both sides by 2
2x/2=-1/2
x=-1/2
Answer:
8x+8
Step-by-step explanation:
(f.g)(x)= (f)(g)
(f.g)(x)=(4.2)(x+1)
(f.g)(x)=(8)(x+1)
(f.g)(x) =8x+8
Answer:
Firstly you need to put the equation in form of. y =ax+b
Let us do it
We have
2x-2y=18
-2y=18-2x
-y=(18) /2 - (2x)/2
-y =9-x
Mutiply by - to remove it beside y
Y=-9+x
Which is y=x-9
Slope =a=1
Yintercept=b=-9
