Given the system of equations:

y = -3x + 4

y = -3x - 2

Let's determine if the two have a solution or not by substituting one equation to the other.

Substitute y = -3x + 4 to y = -3x - 2.

$\text{ y = -3x - 2}$ $\text{ -3x + 4 = -3x - 2}$ $\text{ -3x + 3x }=\text{ -2 - 4}$ $\text{ 0 = -6 : 0 }\ne\text{ -6}$

Therefore, the two systems of equations have no solution.

when Apple sells their iPads they increase the price $50 from what it cost then to actually make the iPads one Apple Store sold

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.

‘| |’ means modulus.
It’s turns the internal value positive.
We get a negative answer while finding the area of a triangle because there points in the quadrant other than the 1st quandrant i.e where all values are positive
Area of a triangle can never be negative, so we use modulus
