♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

y = ( {x}^{2}  + 2x + 1) - 1

y =  ({x + 1})^{2} - 1

y =  ({x + 1})^{2} -  ({1})^{2}

We're done now but I have something to tell...

##############################

Hint :

{a}^{2} -  {b}^{2}  = (a + b)(a - b)

##############################

y = ( \: (x + 1)  + 1)( \: (x + 1) - 1) \\

y = (x + 2)(x)

When Stretch Gordon signed a contract to play basketball for the Toronto Raptors, he received a one-time $250 000 signing bonus.
creativ13 [48]

Answer:

Here's what I get  

Step-by-step explanation:

Stretch

(i) The equation

E = 250 000 + 100 000n

(ii) Variables

n = the number of games played

E = Stretch's total earnings in dollars

(iii) Constants

$250 000 = Stretch's signing bonus

$100 000  = the money earned for each game.

\begin{array}{ccc}\textbf{Games played} & \textbf{ Earnings/}\mathbf{\$}&\textbf{Earnings/}\mathbf{\$10^{6}} \\20 & 2 350 000 &2.35\\40 & 4 250 000&4.25 \\60 & 6 150 000 &6.15\\80 & 8 050 000&8.05 \\\end{array}

The graph shows how Stretch's total earnings vary with the number of games played.

(iv) Total earnings after 44 games

\begin{array}{rcl}E & = & 250000 + 100000n\\& = &250000 + 100000(44)\\& = &250000 + 4400000\\& = & \mathbf{4 650 000}\\\end{array}

Rory

E = 95 000n + 450 000

Rory's deal is better than Stretch's if they play fewer than 40 games.  

He starts off with a bigger signing bonus, but Stretch earns more money per game.

Stretch closes the gap with each game played.

By 40 games they have the same total earnings.

After 40 games Stretch has more total earnings.
