(x - 2)(x - (-1))(x - (-5)) = (x - 2)(x + 1)(x + 5)
Polygon C CC has an area of 40 4040 square units. Kennan drew a scaled version of Polygon C CC using a scale factor of 1 2 2 1
1 answer:
Answer:
10 square units.
Step-by-step explanation:
Area of Polygon C = 40 square units.
Scale factor used in obtaining polygon D =
To obtain the area of the new polygon, we multiply the area of the polygon from which it was derived by the square of the scale factor.
Therefore:
Area of Polygon D
The area of polygon D is 10 square units.

(5) Graph:
(6) Solutions: (-1, -5) and (-2, -7)
Not solutions: (1, 1) and (-4, -3)
EXPLANATION
(5) To graph this system, first, we have to graph each of the inequalities. Both are linear, so we have to graph each line with a dashed line - this is because they are "less than" the line, so the line is not included, and shade the area below each of them.
The first inequality is y < -3x-4,
The second inequality is y < 2x - 1,
The graph of the system is the area shared by both graphs,
(6) Any point that is inside the shaded area is a solution of the system. For example, points (-1, -5) and (-2,-7) are solutions to the system.
On the other hand, any point outside that area, or on the dashed lines is not a solution. For example, points (1, 1) and (-4, -3) are not solutions
