If f(x)=20, what does x equal?

Mathematics
1 answer:
Snowcat [4.5K]3 years ago
3 0

Answer:

20

Step-by-step explanation:

X=20 because f (20) would also be 20. Since we don't know the value behind 20, we would suppose x is the value. The original equation is now f(x)=x. If we do f(20)=x we would get that (since x is being substituted) f(20)=20.

(8/9)^2 is just 8/9 squared, or 8/9 * 8/9. This is 64/81, and cannot be reduced. This is therefore our answer.

Solve. 9(x+1)=4-2(9x+5)
Sindrei [870]

Answer:

-5/9

Step-by-step explanation:

9(x+1)=4-2(9x+5)

Distribute

9x+9=4-18x-10

Add 4 and -10

9x+9=-6-18x

Move -18 to the left side and change sign

9x+9+18x=-6

Move 9 over and change sign

9x+18x=-6-9

Combine like terms

27x=-15

Divide both sides by 27

X=-5/9
