The geometrical relationships between the straight lines AB and CD is that they are parallel to each other
<h3>How to determine the relationship</h3>
It is important to note the following;
- A drawn from the origin and passes through point A (a , b), then the equation of OA = ax + by
- If a line is drawn from the origin and passes through point B (c , d), then the equation of OB = cx + dy
We find the equation of AB by subtracting OB from OA, thus AB = (c - a)x + (d - b)y
The slope of line AB =
⇒ OA= 2 x + 9 y
⇒ OA = 4 x + 8 y
⇒AB = OB - OA
⇒AB = (4 x + 8 y) - (2 x + 9 y)
⇒ AB = 4 x + 8 y - 2 x - 9 y
Collect like terms
⇒ AB = (4 x - 2 x) + (8 y - 9 y)
⇒AB = 2 x + -y
⇒ AB = 2 x - y
⇒ Coefficient of x = 2
⇒ Coefficient of y = -1
⇒ The slope of ab =
= 2
For CD
⇒ CD = 4 x - 2 y
⇒Coefficient of x = -4
⇒ Coefficient of y = -2
⇒The slope of cd =
= 2
Note that Parallel lines have same slopes
And Slope of ab = slope of cd
AB // CD
Therefore, the geometrical relationships between the straight lines AB and CD is that they are parallel to each other

Answer:
$51.30
Step-by-step explanation:
First, we find 25% of the original price, then we deduct that from the original price. Then, we find 10% of the price and deduct that also.
The original price is $76.
25% of $76 is:
= $19
We deduct $19 from $76:
76 - 19 = $57
We find 10% of $57:
= $5.7
Deducting this:
57 - 5.7 = $51.30
She will pay $51.30 for the jacket.

Answer:
75 degrees
Step-by-step explanation: the 15 degree angle is adjacent to angle fgd so its 15 and then all of the other angles add up to 90 degrees then you subtract 15 from 90 and get 75. Im not very good at explaining it don't know if im using the right terms but I know how to do it for sure.
