The answer would be 120,635 people live in that city. Let me know if you want me to elaborate.
You put a one becuse it repusents a 10 and your tencly adding a 10
Answer:
f^-1/2(x)=x/1/2-7/2
Step-by-step explanation:
Replace f(x) with y
Y=1/2x+7
Interchange the variable
X=1/2y+7
Solve For y
Rewrite the equation as
1/2y+7=x
Add -7 to both side
1/2y+7-7=x-7
1/2y=x-7
Divide each term with 1/2
1/2y/1/2=x/1/2-7/1/2
Y=x/1/2-7/2
Solve for hand replace with f^-1/2(x)
f^-1/2(x)=x/1/2-7/2
You first need to multiply the whole second equation by to. So, your two equations would then be -8x + 5y = -9 and 8x + 6y = -46. You then add the two equations to get 11y = -55. This would mean you get y = -5. Then you substitute -5 for y in the first equation. This would mean it would be -8x -25 = -9. Then you add 25 to both sides to get -8x = 16. Then you divide both sides by -8 to get x = -2.
