The expression that expresses all possible lengths of segment AB is 27 < AB < 81. The correct option is the second option 27 < AB < 81
<h3>Properties of a triangle</h3>
From the question, we are to determine the expression that expresses all possible lengths of segment AB
From one of the properties of a triangle,
The <u>third side</u> of any triangle is greater than the difference of the other <u>two sides</u>; and the <u>third side</u> of any triangle is lesser than the sum of the <u>two other sides</u>
Then, we can write that
AB < 27 + 54
and
AB > 54 - 27
Putting the two inequalities together, we get
54 - 27 < AB < 27 + 54
27 < AB < 81
Hence, the expression that expresses all possible lengths of segment AB is 27 < AB < 81. The correct option is the second option 27 < AB < 81

Answer:
y=2x +1/2
Step-by-step explanation:
The solution for the system of equations are:

Attached is the graph of lines y=3x-2 and y=-2x+5.
Answer: The discount is $30, making the sale price $270.
Step-by-step explanation: Take your initial value times the percent of your discount to find the discount amount: in this case, it is 300 * .10 = 30. Then you can subtract that value from your initial value, 300-30=270 to get the sale price.
So basically just add the equations to get rid of y. Then solve for x and plug into one of the equations for y. (1,4)
