Answer: First option.
Step-by-step explanation:
Given the equation , you need to substitute into this equation. Then:
Remember that the Addition property of equality states that:
Then, you can add "x" and 4 to both sides.
Therefore, you get the equation written in function notation, with "x" as the independent variable:
To determine the perimeter of the trapezoid, we just have to determine the distance between the pair of points which can be calculated through the equation,
d = √(x₂ - x₁)² + (y₂ - y₁)²
Substituting,
(1,4) and (-2,0) d = √(1 - -2)² + (4 - 0)² = 5
(-2,0) and (7,0) d= √(-2 - 7)² + (0 - 0)² = 9
(7,0) and (3,4) d = √(7 - 3)² + (0 - 4)² = 5.66
(3,4) and (1,4) d = √(3 - 1)² + (0 - 0)² = 2
The perimeter is the sum of the distances. Thus, the answer is 21.66.
First your take 55 and divide it by 20 to find out have many feet is equivalent to 1 inch. 2.75 feet is equivalent to 1 inch. then you divide that by 8 to find your 1/8 inch equivalent. 2.75/ 8 is equal to .34 feet per 1/8 inch.
Step-by-step explanation:
a. s = n/8
b. the independent variable is s
the dependent variable is n
