Answer:

coordinates of B are (-5, 3/2)

Step-by-step explanation:

equation :

x =    m1 × x2 + m2 × x1                         y =  m1 × y2 + m2 × y1

       _____________                                 _____________

              m1 + m2                                             m1 + m2

x =  (1 × -3) + (1 × -7)                                    y=  (1 × 2) + (1 × 1)

  _____________                                      ____________

          1 + 1                                                           1 + 1

x = (-3 + -7)/ 2 = -10/ 2 = -5                                y = (2+ 1)/2 = 3/2

                                ∴coordinates of B are (-5, 3/2)

What is the absolute value of a number ?
stepladder [879]

Answer:

Step-by-step explanation:

The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5. The absolute value of a number may be thought of as its distance from zero along real number line.
