If g(x ) = 3x - 5, then g -1(x )=
NemiM [27]
G(x) = 3x - 5

let g(x) = y

y = 3x - 5

y + 5 = 3x

3x = y + 5

x = (y + 5)/3

From y = g(x),  x = g⁻¹(y) 

<span>x = (y + 5)/3
</span>
 g⁻¹(y)  = <span>(y + 5)/3</span>

 g⁻¹(x)  = <span>(x + 5)/3</span>

If pencils sell at 6 for 59 cents how many pencils can be bought for 2.95
Olegator [25]
We already know from the given data that 6 pencils can be bought for 59 cents. We have to determine the number of pencils that can be bought for $2.95.
So
Price of 6 pencils = 59 cents.
Price of 1 pencil = (59/6) cents
                           = 9.83 cents
Now total amount in hand for buying pencils = $2.95
                                                                       = 295 cents
Then the number of pencils that can be bought for 295 cents = (295/9.83)
                                                                                                   = 30.01
So the maximum number of pencils that can be bought for $2.95 is 30 pencils.
