Answer:
a: AB is perpendicular to CD
b: AM is equal in length to BM
Answer:
(-4,1) then becomes (0,1)
Step-by-step explanation:
Simply reflections. There are formulas for that.
Answer:
6y + 5x = -54
Step-by-step explanation:
y = m x + b -> slope-intercept form
ax + by = c -> standard form

6y = -5x - 54
6y + 5x = -54
Number 1: (-1+2i)+(6-9i)

Number 2: (3-3i)-(4+7i)

Number 3: (-5+2i)+(-2+8i)

Answer:
A. The circle has been shifted 3 units to the right and 8 units down, r=6
Step-by-step explanation:
Recall that the equation of a circle is
where
is the center of the circle and
is the radius.
Given that the equation is
, this tells us that the center of the circle is at
and the radius is
. Since the value of
represents the amount of horizontal shift from the origin and
represents the amount of vertical shift from the origin, then the circle was shifted 3 units to the right and 8 units down.
