Answer:

D. None of the choices are correct.

Step-by-step explanation:

If <em>B</em> is the midpoint of AC, then that means that AB is congruent to BC. Because this is true, you can set 8x + 4 and 10x - 8 equal.

8x + 4 = 10x - 8

Now just solve for x. Subtract 8x from both sides and add 8 to both sides.

4 = 2x - 8

12 = 2x

Then divide by 2.

6 = x

Another way to do this problem is to set up the same equation, but instead of solving it, plug in answer choices A, B, and C independently of each other. Then simplify to see if those are right. You'll find out that none of them are.

What is the slope of the line perpendicular to the line with equation 4x-5y+13=0

motikmotik

Answer:

m = - 5/4

Step-by-step explanation:

If two lines are perpendicular, their slopes are negative reciprocals, which means that their product is -1

We can write the equation

4*x - 5*y + 13 = 0

as: 5*y = 4*x + 13 or

y = (4/5)*x + 13 (1)

Equation (1) is the equation of a straight line in its slope point form, 4/5 is the slope, according to this the slope of a perpendicular line is
