You would divide 27 by 12.
27 / 12 = 2.25
So, he used 2.25 pounds per sandwich.
<span>So
I only have ones, tens and hundreds block. I need to find a way how can I fit
the given number 1 718.
=> Since I have hundreds block, I can divide 1 718 by 100
=> 1 718 / 100, how many 100s are there in 1 718
=> 17 hundreds
=> now we only have 18 left
=> 18 / 10, how many 10s are there in 18
=> 1 tens
=> Now we only have 8 left
=> 8 / 1, how many ones are there in 8
=> 8
=> 17 hundreds, 1 tens, and 8 ones.</span><span>

Answer:
a) Since the function is given to be one - one so the inverse of the function exist. Now f(x) maps x to y so the inverse of f(x) maps y to x
To find inverse, first interchange the roles of x and y :
Now, solve for y :
b) To find coordinates of f(x) :
First take y = 0 then take x = 0
⇒ x-coordinates : (-125,0) and y-coordinates : (0,5)
To find coordinates of inverse function of x :
First take y = 0 then take x = 0
⇒ x - coordinates : (5,0) and y - coordinates : (0,-125)
c) f(x) is defined for every real number.
⇒ Domain : -∞ < x < ∞
and Range : -∞ < f(x) < ∞
And inverse function of x is also defined for every real number :
⇒ Domain : -∞ < x < ∞
Answer:
5x² + 15x + 5
Step-by-step explanation:
Here's one way to do it.
Put corresponding powers of x beneath each other and add the similar terms.
5x² + 3x - 7
<u> 12x + 12
</u>
5x² + 15x + 5
