Is Point M the midpoint of AB? Select Yes or No for each statement.
Minchanka [31]

Answer:

A). Yes

B). Yes

C). No

D). Yes

Step-by-step explanation:

Coordinates of the midpoint of a segment joining two points (x_1, y_1) and (x_2,y_2) are given by (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}).

A). If the points are A(1, 2) and B(3, 4)

    Coordinates of the midpoint M → (\frac{1+3}{2},\frac{2+4}{2})

    M → (2, 3)

    Yes.

B). Extreme points of segment AB are A(0, 8) and B(10, -1)

    Coordinates of the midpoint will be,

    M → (\frac{0+10}{2}, \frac{8-1}{2})

    M → (5, 3.5)

    Yes

C). Extreme points of segment AB are A(-7, -5) and B(6, 4)

    Coordinates of the midpoint will be,

     M → (\frac{-7+6}{2}, \frac{-5+4}{2})

     M → (-0.5, -0.5)

     NO

D). Extreme points of segment AB are A(4, -2) and B(6, -8)

     Coordinates of the midpoint will be,

     M → (\frac{4+6}{2}, \frac{-2-8}{2})

     M → (5, -5)

     Yes

Identify the solution set of 3 In 4 = 2 In x.<br> 0 {6}<br> O {-8, 8)<br> O {8}
Aleksandr-060686 [28]

Answer:

<em>x = 8 </em>

Step-by-step explanation:

3 ln 4 = 2 ln x  ( <em>x > 0</em> )

ln 4^{3} = ln x^{2}

x² = 4³

x² = (2³)²

x = ± 2³

x_{1} = 8

x_{2} = - 8 ( strange root, does not satisfy the domain of given function )

<em>x = 8</em>
