Answer:

D)\frac{B}{A} =\frac{C}{D}

Step-by-step explanation:

Remember that parallel lines have the same slope, and the formula for slope is:

m=\frac{y2-y1}{x2-x1}

So now, if you insert the values of each line, you would get:

Point 2 line 1 (0,B)O

Point 1 line 1  (-A,0)

Insert into the formula:

m=\frac{y2-y1}{x2-x1}\\m=\frac{B-0}{0-(-A)}\\m=\frac{B}{A}

That is the slope of line 1.

Point 2 line 2 (D,0)

Point 1 line 2 (0,-C)

Insert into the formula:

m=\frac{y2-y1}{x2-x1}\\m=\frac{0-(-C)}{D-0}\\m=\frac{C}{D}

So the slope for the line number 2 is: m=\frac{C}{D}

If both slopes are equal we can prove that they are parallel, so the correct option would be D)\frac{B}{A} =\frac{C}{D}

I would say that the correct answer is D. because y is always the numerator while x is the denominator for the equation y2 - y1/x2 - x1 which means if there is two y's or two x's on the same line you subtract the second one from the first one. If there is only one y and/or x and the other is 0 on the same line, it stays at y or x without subtracting y2 - y1 or x2 - x1. 

Since b is on the y coordinate and -a is on the x coordinate, you would make it b/a while -a is gonna be a positive since the lines are going up and to the right. Now, since c is the y coordinate and d is the x coordinate, make C the numerator and d the denominator since y is always the numerator and x is the denominator for these parallel line figures on the graph and the equation will be equaled to the fraction to the other fraction for parallel lines. 

So, your answer would be D. b/a = c/d 

Hope this helps, and is correct!

A ball is dropped from the top of a building that is 250 feet tall. The
Virty [35]

hi

-16t²+250 = 75

-16t² = 75 -250

-16t² = -175

  t² = -175 /-16

 t² = 175/16

Here there si two solutions :  t = \sqrt{175/16}   and  t =  - \sqrt{175/16}

However, as time cannot rewind,  we will  keep only positive solution

So t = \sqrt{175/16}

   

in seconds  it will be  :  3.3 seconds

What is the x-intercept for the following linear equation:
Alexandra [31]
The "x-intercept" occurs when y=0, because it is at this point that the equation touches the x axis.  So if you plug in y=0 into the equation you can solve for the x coordinate.

4x-2(0)-8=0

4x-8=0

4x=8

x=2

So the x-intercept is the point (2,0)
