Answer:
- The inequality translated in numerical form
Step-by-step explanation:
The mean is the average, or when you add all the numbers and divide it by how many numbers there are. And the mode is how frequently some number appears in a set of numbers. (For example- 1,1,1, 4,9,1,6,13,6 ---> the mode is one.)
Answer:
see explanation
Step-by-step explanation:
The axis of symmetry is at the midpoint of the zeros
To find the zeros equate y to 0, that is
x² - 2x = 0 ← take out a common factor x
x(x - 2) = 0
equate each factor to zero and solve for x
x = 0
x - 2 = 0 ⇒ x = 2
x = ⇒ x = 1 ← equation of axis of symmetry
The vertex lies on the axis of symmetry with x-coordinate = 1
Substitute x = 1 into the equation for corresponding value of y
x = 1 : y = 1² - 2(1) = 1 - 2 = - 1
vertex = (1, - 1)
(8j3 - 5j2 - 5) - (6j3 - 12j2 + 8j - 7) =
(8j3 - 6j3) - (5j2 - 12j2) - 8j - (5-7) =
2j3 - (-7j2) - 8j - (-2) =
2j3 + 7j2 - 8j + 2
The correct answer is D. 2j3 + 7j2 - 8j + 2
