What's the equation of the line that's a perpendicular bisector of the segment connecting C (6, –12) and D (10, –8)? answers: A)
vitfil [10]

Answer:

A

Step-by-step explanation:

Perpendicular bisector of a line divides the line into 2 equal parts and it is perpendicular to the line.

First let's find the midpoint of CD. The point is where the perpendicular bisector will cut through the line.

midpoint= ( \frac{x1 + x2}{2} ,  \frac{y1 + y2}{2} )

Thus, midpoint of CD

= ( \frac{6 + 10}{2} , \frac{ - 12 - 8}{2} ) \\  = ( \frac{16}{2} , \frac{ - 20}{2} ) \\  = (8, - 10)

Gradient of line CD

=  \frac{y1 - y2}{x1 - x2}  \\  =  \frac{ - 12 -  ( - 8)}{6 - 10}  \\  =  \frac{ - 12 + 8}{ - 4} \\  =  \frac{ - 4}{ - 4}  \\  = 1

The product of the gradients of perpendicular lines is -1.

gradient if perpendicular bisector(1)= -1

gradient of perpendicular bisector= -1

y=mx +c, where m is the gradient and c is the y-intercept.

y= -x +c

Subst a coordinate to find c.

<em>Since the perpendicular bisector passes through the point (8, -10):</em>

When x=8, y= -10,

-10= -8 +c

c= -10 +8

c= -2

Thus, the equation of the perpendicular bisector is y= -x -2.

How many solutions are there to the equation below?
elena55 [62]

Answer:

A) 0 (no solutions)

Step-by-step explanation:

Solve the equation:

3x - 10(x+2) = 13 - 7x

3x - 10x -20 = 13 - 7x

-7x - 20 = 13 - 7x

-20 = 13

Since both sides are clearly not equal to each other, no solution can satisfy both sides to be equal to each other. So A is correct.
