In order to solve this question
Make an equation
Let x be the cost of each T- shirt
75x+6.25-20=398.75
Simplify the equation
75x-13.75= 398.75
Get Rid of The Constant
75x-13.75+13.75= 398.75+13.75
75x=412.5
Make sure your Variable is equal to one
75x÷75= 412.5÷75
x= 5.5
The price of each shirt is $5.50
Step-by-step explanation:
Here is how you find the answer: (not "bUt JuSt UsE yOuR cAlCuLaToR")
Factor x3−18x+27
x3−18x+27
=(x−3)(x2+3x−9)
Hope this helps!!!!!!!
The first answer is that the system represents 2 lines. They are two parallel lines.
For the second question, it just represents 1 line. In this case, the two lines are right on top of each other. This is because they are the same equation, just in different forms.
