Answer:
- 5x² - 11x + 2
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
f(x) + g(x)
= - 4x² - 6x - 1 + (- x² - 5x + 3)
= - 4x² - 6x - 1 - x² - 5x + 3 ← collect like terms
= - 5x² - 11x + 2

Answer:
C. 2,150
Step-by-step explanation:
We know that out of 120 passengers, 86 were satisfied with the service.
To find the percentage amount of passengers who were satisfied, we can divide 86 by 120 and get 0.716 repeating (about 71.6%).
Then, we can multiply the total number of passengers, 3,000, by that number and get 2,150.
Answer:
B. rotation 90° counterclockwise about the origin.
Step-by-step explanation:
Transformation is the process by which the size or orientation of a given figure is altered without any effect on its shape. Examples are; rotation, reflection, translation and dilation.
Rotation is the process of turning a figure about a reference point called the origin. While reflection is turning a figure about a line to produce its image.
In the given question, ∆ABC is mapped onto ∆A'B'C' by rotating it at 90° counterclockwise about the origin.
