The answer is C because if you substitute in X-6 for the y in the first equation (since X-6 is also equal to y), you get 2x=16 which means x=8. There is only one option where 8 is equal to X, but just to check you can substitute it back into either of the original equations to make sure that y=2.

If f(x) = 2x - 2 and g(x) = x}, what is (gºf)(4)?
Bad White [126]

Answer:

We conclude that:

(gºf)(4) = g(f(4)) = g(6) = 6

Step-by-step explanation:

Given

f(x) = 2x - 2

g(x) = x

We have to determine (gºf)(4).

(gºf)(4) = g(f(4))

f(4) = 2(4)-2

      = 8 - 2

      = 6

Thus,

(gºf)(4) = g(f(4)) = g(6) = 6

Therefore, we conclude that:

(gºf)(4) = g(f(4)) = g(6) = 6

Complete the recursive formula of the geometric sequence -0.56\,,-5.6\,,-56\,,-560,...−0.56,−5.6,−56,−560,...Minus, 0, point, 56
pentagon [3]

Answer:

The recursive formula is:

Cn = 10C(n-1)

Step-by-step explanation:

Given the geometric sequence.

-0.56, -5.6, -56, -560, ...

The common ratio is

-5.6/-0.56 = -56/-5.6 = -560/-56 = ... = 10

The recursive formula is easily

Cn = C(n-1) × 10

That is a number is ten times the preceding number.

Answer:

144'

Step-by-step explanation:

Your ratio is 45'/5" or 9:1

9x4"=36'

9x3"=27'

45+36+36+27=144'

I believe this is the same answer as I gave previously.
