Based on the concept of coordinates and the available information, the correct answer is option D. (y2 - y1)(y4 - y3) = (x2 - x1)(x4 - x3)
Coordinate is a mathematical term that is used to describe the values on which mathematical operations occur in an algebraic expression.
In this case, to determine if AB is parallel to CD check if the slopes of the two lines are equal since parallel lines have the same slope.
The slope of a line passing through two points (x1 y1) and (x2 y2) is given by the formula:
m = (y2 - y1) / (x2 - x1)
So the slope of line AB is:
m_AB = (y2 - y1) / (x2 - x1)
And the slope of line CD is:
m_CD = (y4 - y3) / (x4 - x3)
If AB is parallel to CD then the slopes m_AB and m_CD should be equal.
Therefore the condition to prove that AB is parallel to CD is:
m_AB = m_CD
If the condition m_AB = m_CD is true it proves that line AB is parallel to line CD.
Hence, in this case, the correct answer is option D. (y2 - y1)(y4 - y3) = (x2 - x1)(x4 - x3)

3. (x-4)² =169
please help me answer these :)
Negative 20
The expression simplifies to 20, as of the given operations.
To calculate the expression , we follow the order of operations (PEMDAS/BODMAS).
First, we evaluate the parentheses: (4 - 2) = 2.
Next, we calculate the cube of 2³= 8.
Then, we subtract 3 from 8:
8 - 3 = 5.
Finally, we multiply the result by 4:
5 × 4 = 20.
Therefore, the value of the expression is 20.

Answer:
-4
Step-by-step explanation:
(4-2)³ = 8
so 8 - 3 x 4
is equal to -4
b. x ≈ −0.76 and x ≈ 5.26
c. x ≈ −1.22 and x ≈ −3.28
d. x ≈ −5.26 and x ≈ 0.76
Answer:
The roots of the equations are x ≈ -5.26 and x ≈ 0.76 .
Option (d) is correct.
Step-by-step explanation:
Formula for the roots is given by .
As the equation in the form
As the equation in the form ax² + bx + c = 0
a = 2, b= 9 , c = -8
Put in the formula
Thus First roots be
x ≈ -5.26
The second root be
x ≈ 0.76
Therefore the roots of the equations are x ≈ -5.26 and x ≈ 0.76 .
Option (d) is correct.
