What is the slope of the line that passes through the points (7, -4) and (7, 0)? A. Undefined (vertical line) B. 0 (horizontal line) C. 1 D. Infinity
Answers
Answer: A (Vertical Lines)
Step-by-step explanation:
Final answer:
The slope of a line passing through points (7,-4) and (7,0) is undefined. This is because a line with the same x-coordinate for two different y-coordinates implies a vertical line, which has an undefined slope. Therefore, the correct answer is A. Undefined (vertical line).
Explanation:
The slope of a line passing through two points (x1,y1) and (x2,y2) is defined by the formula slope = (y2 - y1) / (x2 - x1). Given the two points are (7,-4) and (7,0), we use the formula and get slope = (0 - (-4)) / (7 - 7). This results in 0/0 which is undefined mathematically. Furthermore, when a line has the same x-coordinate for two different y-coordinates, it implies the line is vertical. Thus, we can decide that the line passing through those points is indeed a vertical line, and the slope is undefined; as vertical lines have undefined slopes.

Explanation:
There is a theorem in geometry that says:
In a circle, if two chords are equal in measure, then their corresponding minor arcs are equal in measure.
Those small tick marks on each of the chords means that they are equal in measure. So, following the theorem, the arcs are also equal in measure.
If they are equal and
arc AB = arc CB
arc AB = 24 feet
Then
arc CB = 24 feet
by substitution.

Original cost of the car is $21,000.
What is Percentage?
A relative value indicating hundredth part of any quantity is called percentage.
Given that;
A new car lose 20% of its value.
In first year, A car lost $4,200 of the value.
Now, Let original price of car = $x
Then, By the given condition;
20% of x = $4,200
Solve for x;
20/100 of x = 4,200
20/100 × x = 4,200
1/5 × x = 4,200
x = 5 × 4,200
x = 21,000
Thus, Original cost of the car is $21,000.

Yeah umm I'm doing my homework and the answer was ACTUALLY 2x... Soooo....
so in this case you have to multiply x by 1, which results in 1x or x
the answer is x
