The problem is stating that Mandy found the ratio between input and output of many points on the graph, which are displayed by the fractions. Mandy's conclusion was that they were not equivalent, meaning they were different and that is why the function is not proportional. Mandy's conclusion is wrong, the relation is proportional. If we take all the functions we have:
Where the input is the denominator and the output is the numerator we will have a ratio of "5". Mandy's mistake was to invert the last fraction, she inserted the output in the denominator, this is why she said the were different.

Answer:
A = 48 square units
Step-by-step explanation:
The dimensions between two markings on the coordinate plane = 2 unit
The trapezoid is located sideways
The area of a trapezoid, A = ((a + b)/2) × h
Where;
a = The long base side
b = The short base side
h = The height
The long base side length AT = 4 space between markings = 4 × 2 units = 8 units
The short base side length SR = 2 space between markings = 2 × 2 units = 4 units
The height, h = 4 space between markings = 4 × 2 units = 8 units
The area of the trapezoid, A = ((4 unit + 8 unit)/2) × 8 unit = 48 square units.
285 + 617 = 902
902 - 620 = 282
Answer: 282
Answer:
see explanation
Step-by-step explanation:
Given
(a + bi)(a - bi) ← expand using FOIL
= a² - abi + abi - b²i² → i² = - 1
= a² + b²
Since a and b are any real numbers, then
a² + b² is a real number
B
When a complex number is multiplied by its conjugate the result is always real.
