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.
Answer:
x=-1
Step-by-step explanation:
4(x-3(-2))=6(x-3(-2)) => 4(x+6)=6(x+6) => 4x+24=6x+26 => -2=2x => x=-1
The answer would be 1.52727...
To solve this, subtract 283-199 is 84. Then divide 84 by 55 since 55 is mph of the car. Then you would divide the 84/55. After, the calculation should be 1.52727...
So, the answer/ how much time it takes from Tallahassee to Live Oak is 1.5 hours. (1.52727, 1.53)
Is there supposed to be an equation that follows? Can I see the entire question?
Answer:
x=5, y=8
Step-by-step explanation:
Since both equations equal y, we can set them equal
y = x + 3
y = 2x - 2
x+3 = 2x-2
Subtract x from each side
x-x+3 = 2x-x-2
3 = x-2
Add 2 to each side
3+2= x-2+2
5 =x
Now we need to find y
y =x+3
y=5+3
y=8
