2. (-5,-4)
3. (-20,11)
4. (2,3)
5. (13/7, 40/7)
Answer:
c = 2
Step-by-step explanation:
Substitute x = 1 + i into the equation
(1 + i)² - 2(1 + i) + c = 0 ← distribute left side
1 + 2i + i² - 2 - 2i + c = 0 ( note that i² = - 1 )
1 + 2i - 1 - 2 - 2i + c = 0 ← collect like terms on left
- 2 + c = 0 ( add 2 to both sides )
c = 2
Answer:
D. 12 units
Step-by-step explanation:
The distance between two points is found by
d = sqrt( (x2-x1)^2 + (y2-y1)^2)
sqrt( (4 -4)^2 + (-5-7)^2)
sqrt((0^2 + (-12)^2)
sqrt(0+144)
sqrt(144)

Answer:
(x,y) = (3x,3y)
Step-by-step explanation:
Answer:
{(-5, 3), (2, -5), (2, 9), (3, -6), (5, -3)}
Step-by-step explanation:
Start on the left side, that number is the x.
List them in pairs the left x number with the right y number it points to.
