Answer:

Step-by-step explanation:
The given relation is

where
is the portion of walkway in which the person walks
Rearranging the equation we get

The length of the portion of the walkway labeled
is
.
Given y + 3.5 = 0.75(x - 2)
when x = 4,
y + 3.5 = 0.75(4 - 2) = 0.75(2) = 1.5
y = 1.5 - 3.5 = -2.
Thus, the ordered pair (4, -2) is the line with equation y + 3.5 = 0.75(x - 2)
When x = -4,
y + 3.5 = 0.75(-4 - 2) = 0.75(-6) = -4.5
y = -4.5 - 3.5 = -8
Thus, the ordered pair (-4, -8) is the line with equation y + 3.5 = 0.75(x - 2)
When x = 1,
y + 3.5 = 0.75(1 - 2) = 0.75(-1) = -0.75
y = -0.75 - 3.5 = -4.25
Thus, the ordered pair (1, 1.75) is not on the line with equation y + 3.5 = 0.75(x - 2)
When x = 7,
y + 3.5 = 0.75(7 - 2) = 0.75(5) = 3.75
y = 3.75 - 3.5 = 0.25
Thus, the ordered pair (7, 0.25) is not on the line with equation y + 3.5 = 0.75(x - 2)
7,3), (-2, 3), (3,-2) 0 (-7, -3), (-2, 3), (2, -3)
Answer:
The correct option is 4.
Step-by-step explanation:
The non parallel sides of an isosceles trapezoid are congruent.
The image of an isosceles trapezoid is same as the preimage of isosceles trapezoid if
1. Reflection across a line joining the midpoints of parallel sides.
2. Rotation by 360° about its center.
3. Rotation by 360° about origin.
If we rotate the trapezoid by 180° about its center, then the parallel sides will interchanged.
If we reflect the trapezoid across a diagonal, then the resultant figure will be a parallelogram.
If we reflect across a line joining the midpoints of the nonparallel sides, then the parallel sides will interchanged.
After rotation by 360° about the center, we always get an onto figure.
Therefore option 4 is correct.
