A number times 1 always equals itself, so: 4×1 = 4, OR 2×2 = 4
Considering that 160,000 is the y-intercept of the function, it's significance is given by:
the initial population at the time of the estimation.
<h3>What is the y-intercept of a function f(x)?</h3>
The y-intercept is f(0), that is, the value of y when x = 0, which is interpreted as the initial value of the function.
Researching this problem on the internet, it is found that f(0) = 160,000, hence the significance of 160,000 in the function is given by:
the initial population at the time of the estimation.

|a| = b gives
a =b or a = -b
so,
|-x| = -10
gives
-x = -10 or -x = 10
x = 10, -10
now let us verify,
when x = 10, |-10| = +10 and it is not = -10
so, x= 10 is NOT a solution.
when x = -10, |-(-10)| = |10| = 10 and it is not = -10
so, x= -10 is NOT a solution.
hence, this equation does not have a solution.
If we know that |...| can never be negative, we can directly deduce that this equation does not have any solution.
First things you have to do is figure out how much they increased the iPads by:
$50 • 10 = $500
They increased the iPad price by $500.
Subtract the total amount from the iPad price:
$5,000 - $500 = $4,500
The actual price of 10 iPads, without an increase is $4,500
Now divide that by 10 to get the amount for one iPad:
$4,500 ÷ 10 = $450
One iPad actually costs $450 to make.
