Find the inverse, g−1(x), of the following function: g(x) = 4x - 11
Sphinxa [80]

Answer:

g^{-1} (x) = \frac{x+11}{4}

Step-by-step explanation:

let y = g(x) and rearrange making x the subject, that is

y = 4x - 11 ( add 11 to both sides )

y + 11 = 4x ( divide both sides by 4 )

\frac{y+11}{4} = x

Change y back into terms of x , with x = g^{-1} (x) , thus

g^{-1}(x) = \frac{x+11}{4}

the area of a rectangle is 42.15 square meters. if the length is 21 meters, what is perimeters of the rectangle?
Vsevolod [243]

Answer:

perimeters of the rectangle=p=46.014 metres

Step-by-step explanation:

Given that:

Length (l) = 21 m

Area of rectangle(A) = 42.15 meter-square

Width (w)=?

Required data:

Perimater of Rectangle=p=?

Calculation:

As we know that Area of rectangle=A=l*w

Putting the value we get

42.15 m(square)=(21 m)*w

or w=42.15/21

or w=2.007 m

Now to find perimters of rectangle we know that

p=2(l + w) metres

putting the values

p=2(21+2.007) metres

p=2(23.007) metres

p=46.014 metres

Hey salesman needed to settle for Willie he priced at $3500 the first day it was on the market the second he reduced it by 10% w
nataly862011 [7]

Answer:

The price of the four wheeler after with the reduction is $3,150.

Step-by-step explanation:

The original price of the Willa = $3500

The reduction percentage = 10%

Now, 10% of $ 3500 = \frac{10}{100}  \times 3500 = 350

So, the reduction amount is $350.

So, the reduced price of Willa = The original price - The reduced price

= $3500 - $350.  = $3,150.

Hence,  price of the four wheeler after with the reduction is $3,150.
