Answer:

Step-by-step explanation:

You are given two complex numbers -i and 2+i.

For the complex number z=x+iy, the ordered pair (x,y) represents this complex number on the coordinate plane.

So, the numbers:

$-i=0-1\cdot i$ is represented by the ordered pair (0,-1)
$2+i=2+1\cdot i$ is represented by the ordered pair (2,1).

Plot these two points on the coordinate plane and coonect them with a straight line. You'll get the last option of graph.

Talja [164]

Answer:

$-2\dfrac{1}{4}\div\left(-\dfrac{2}{3}\right)=\dfrac{27}{8}=3\dfrac{3}{8}}$

Step-by-step explanation:

$-2\dfrac{1}{4}\div\left(-\dfrac{2}{3}\right)\qquad\text{the quotient of two negative numbers is positive}\\\\=2\dfrac{1}{4}\div\dfrac{2}{3}\qquad\text{convert the mixed number to the improper fraction}\\\\=\dfrac{2\cdot4+1}{4}\div\dfrac{2}{3}=\dfrac{9}{4}\div\dfrac{2}{3}\\\\\text{dividing by a fraction is the same as multiplying by its reciprocal.}\\\\=\dfrac{9}{4}\cdot\dfrac{3}{2}=\dfrac{9\cdot3}{4\cdot2}=\dfrac{27}{8}\qquad\text{convert to the mixed number}\\\\=3\dfrac{3}{8}$
