So basically you have to multiply 100 by every single number after it like 100*99*98*97*96......

Hope this helps!

you meant 100!, is a factorial, and yes, your calculator has [ ! ] button for factorials

5! is just 5*4*3*2*1

11! is just 11*10*9*8*7*6*5*4*3*2*1

and so on.

You can buy DVDs at a local store for 15.59 each. You can buy them at on online store for 13.99 each plus $6 shipping. How many

dalvyx [7]

Local(L) = 1 x (15.99)
Online(O) = (1 x 13.99) + 6

So use that equation until you find the same number.

L1=15.99
O1=19.99

L2=31.98
O2=33.98

L3=47.97
O3=47.97

And your answer will be three from local and three from online.

If f(x)=4-11 what is the value of f(5)

Sveta_85 [38]

f(5) = 9

Do this by substitution:

f(x) = 4x - 11

f(5) = 4(5) - 11

f(5) = 20 - 11

f(5) = 9

Find the inverse of the function. Show work. <br> g(x)= - 3/x-2 +2

4vir4ik [10]

Answer:

$\displaystyle g^{-1}(x)=\frac{-7+2x}{x-2}$

Step-by-step explanation:

We are given the function:

$\displaystyle g(x)=-\frac{3}{x-2}+2$

Let's find the inverse of g.

Call y=g(x):

$\displaystyle y=-\frac{3}{x-2}+2$

We need to solve for x. Multiply both sides by x-2 to eliminate denominators:

$y(x-2)=-3+2(x-2)$

Operate:

$yx-2y=-3+2x-4$

Collect the x's to the left side and the rest to the right side of the equation:

$yx-2x=-3-4+2y$

Factor the left side and operate on the right side:

$x(y-2)=-7+2y$

Solve for x:

$\displaystyle x=\frac{-7+2y}{y-2}$

Interchange variables:

$\displaystyle y=\frac{-7+2x}{x-2}$

Call y as the inverse function:

$\boxed{\displaystyle g^{-1}(x)=\frac{-7+2x}{x-2}}$

Maranda is buying pencils and a writing pad for her adult writing class. The writing pad she wants costs $3.50, and each pencil

Kruka [31]

Hello!

3.50 + 0.15 = 3.65

Because both items would cost $3.50 together, Maranda will be eligible to buy them both and stay within her budget of $5.00.
