Step-by-step explanation:
Given ,
f(x)=9-x
g(x)= +x
here,.
fog
=f(g(x))
=f( +x)
=9-( +x)
=9- -x
=9-x-
Answer:
In the year 2000 the number of hazardous waste sites in state y was 21
Step-by-step explanation:
Let
x ----> the number of hazardous waste sites in state x in the year 2000
y ----> the number of hazardous waste sites in state y in the year 2000
we know that
----> equation A
----> equation B
Solve the system of equations by substitution
Substitute equation B in equation A
Solve for y
Adds 8 both sides
Divide by 2 both sides
therefore
In the year 2000 the number of hazardous waste sites in state y was 21
