Answer:
C
Step-by-step explanation:
If we know that x is greater than or equal to 4, then we should substitute 4 in place of x in each possible solution.
A 4 + 3 ≥ 1 True, it's greater, but it can't be equal to.
B 3(4) ≥ 1 It's greater once again, can't be equal to.
C 4 - 3 ≥ 1 If x can also be greater than 4, then it works both ways. Equal and greater than.

The vertices of a figure are given. Find the coordinates of the figure after the transformations given. A(−5,3),B(−2,3),C(−2,1),D(−5,1)Reflect in the y-axis. Then dilate with respect to the origin using a scale factor of 2. (help please))!!!
Answer:
Reflection: A' (5, 3)
B' (2, 3)
C' (2, 1)
D' (5, 1)
Dialation: A"(10, 6)
B" (4, 6)
C" (4, 2)
D" (10, 2)
Step-by-step explanation:
A(−5,3),B(−2,3),C(−2,1),D(−5,1)
To reflect over the y-axis you change the value of x. In this case all of the values for x are negative. You turn them all into a positive.:
A' (5, 3)
B' (2, 3)
C' (2, 1)
D' (5, 1)
To dialate by a scale factor of 2 you multiple everything by 2 and you should get: A"(10, 6)
B" (4, 6)
C" (4, 2)
D" (10, 2)

The figure can be composed of different shapes.
What shapes can the figure be decomposed into to find the area? What is the area?
A. one triangle and one square; 24 square feet
B. one triangle and one rectangle; 30 square feet
C. two triangles and one square; 36 square feet
D. two triangles and one rectangle; 42 square feet
The figure can be composed in to one triangle and one rectangle and the area is 30 square feet.
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
Given is a figure.
We can divide the figure in to one triangle and one rectangle by drawing a vertical line.
Area of a rectangle = Length × Width
Here, length = 8 feet and width = 3 feet
Area of rectangle = 8 × 3 = 24 feet²
Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height
Base = 12 - 8 = 4 feet and height = 3 feet
Area of triangle = [tex]\frac{1}{2}[/tex] × 4 × 3 = 6 feet²
Total area = 24 feet² + 6 feet² = 30 feet²
Hence the area is 30 feet².
