Answer:
A. D=sqrt( (x2-x1)^2+(y2-y1)^2 )
Step-by-step explanation:
The distance between two points is the root of the sum of the squares of the differences in their corresponding coordinates. The equation of choice A is the usual formulation.

<em>Comment on answer choices</em>
Because the square of a number is the same as the square of its opposite, the formula in choice D is also correct.
The a point is refrected through the line y = x, the new point is found by interchanging the x and y-cordinate of the original point. i.e. if the original point is (a, b) and is refrected through the line y = x, the new point will be (b, a).

Answer:
The slope- intercept form this situation is given by y = 0.75x + 3 .
Step-by-step explanation:
The slope- intercept is given by
y = mx + c
Where m is the slope, c is the y intercept .
As given
When visiting Baltimore, MD needs taxi to get from your hotel to the National Aquarium.
The taxi company charges a flat fee of $3.00 for using the taxi and $0.75 per mile.
Let us assume that the total amount charge by the taxi be y .
Let us assume that the number of miles travelled by the taxi be x.
Than
Total amount charge by taxi = Amount charge by the taxi per miles + Flat free charge .
y = 0.75x + 3
(Here m = 0.75 and c = 3)
Therefore the slope- intercept form this situation is given by y = 0.75x + 3 .
Answer:
The fraction is .
Step-by-step explanation:
Eduardo Is thinking of a non-unit fraction with a single-digit denominator.
Assuming the fraction to be .
When Eduardo multiplies his fraction by 5 he gets a mixed number and when he multiplies his fraction by 3 he can simplify the answer.
Therefore, the fraction chosen by Eduardo will be , where x is between 5 and 3.
So, the fraction is .
Again, when he multiplies his fraction by 4 he gets which is a whole number. (Answer)
