3/2 (4)^x = 6144
3/2 4^x = 6144
(2/3)3/2 4^x = 6144(2/3)
4^x = 4,096
4^6 = 4,096
4,096 = 4,096

The midpoint of AB = ([?], [])<br> M = (x¹+x², ¹2²)<br> PLS HELP I WILL MARK BRAINLIEST

OlgaM077 [116]

Answer:

$\sf M=\left(-\dfrac{1}{2},0\right)$

Step-by-step explanation:

Let (x₁, y₁) = Point A = (-2, 1)

Let (x₂, y₂) = Point B = (1, -1)

$\sf Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)$

$\implies \sf Midpoint=\left(\dfrac{-2+1}{2},\dfrac{1+(-1)}{2}\right)$

$\implies \sf Midpoint=\left(-\dfrac{1}{2},0\right)$
