Answer:
+
i
Step-by-step explanation:
Expressing the complex numbers in coordinate form
3 + 8i → (3, 8 )
2 - i → (2, - 1 )
To find the midpoint use the midpoint formula
midpoint = [0.5(3 + 2), 0.5(8 - 1) ] = [0.5(5), 0.5(7) ] = (
,
)
and (
,
) =
+
i
Answer:
Closed circle on 30 shading to the right :)
Step-by-step explanation:
x + y = 18 → 3x + 3y = 54
x - 3y = 22 → x - 3y = 22
4x = 76
4 4
x = 19
x + y = 18
19 + y = 18
- 19 - 19
y = -1
(x, y) = (19, -1)
Answer:
Graphs behave differently at various x-inter cepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Suppose, for example, we graph the function. f(x) = (x+3)(x - 2)²(x+1)³.
Notice in the figure below that the behavior of the function at each of the x-intercepts is different.
Kilogram means one THOUSAND grams. So 800 kilograms equals 800 THOUSAND grams or 800,000 grams.
