Answer: +30

Step-by-step explanation: Before jumping right into this problem, let's just review quickly what the vertical bars mean around 45 - 75.

The vertical lines are called absolute value and we use them around either side of the number. Absolute value means <em>distance from zero</em> on a number line. This will be very important to understand when doing this problem.

Before taking the absolute value of a number, always simplify what's inside the absolute value as much as possible.

So here we have |45 - 75| inside the absolute value which can be thought of as |45 + -75| or -30. So we have |-30| which is +30.

Remember that absolute value means <em>distance</em> <em>from zero</em> on a number line so the absolute value of -30 would be 30 because -30 is 30 units from zero on the number line.

This means that |45-75| is +30.

What is the answer
vichka [17]
An excluded value is one where the bottom of the fraction = 0.

In your case 1-3x=0
1=3x
x=1/3

At this point, the function does not exist. If you were to draw a graph of it, there wouldn't be a y-value corresponding to x=1/3.

A, B , and C are collinear points: B is between A and C. If AB = 36, BC = 5x - 9 , and AC = 54 , find x
balandron [24]

9514 1404 393

Answer:

  x = 5.4

Step-by-step explanation:

The segment sum theorem tells you ...

  AB +BC = AC

  36 +(5x -9) = 54

  5x = 27 . . . . . . . . . . . subtract 27 from both sides

  x = 5.4 . . . . . . . . . . divide by 5
