Write an equation of the perpendicular bisector of the segment with end points M(1,5) and N(7,-1)
vitfil [10]
The perpendicular bisector of the segment passes through the midpoint of this segment. Thus, we will initially find the midpoint P:

P=\dfrac{(1,5)+(7,-1)}{2}=\dfrac{(8,4)}{2}=(4,2)

Now, we will calculate the slope of the segment support line (r). After this, we will use the fact that the perpendicular bisector (p) is perpendicular to r:

m_r=\dfrac{\Delta y}{\Delta x}=\dfrac{5-(-1)}{1-7}=\dfrac{6}{-6}\iff m_r=-1


p\perp r\Longrightarrow m_p\cdot m_r=-1\Longrightarrow m_p\cdot(-1)=-1\iff m_p=1

We can calculate the equation of p by using its slope and its point P:

y-y_P=m_p(x-x_P)\\\\&#10;y-2=1\cdot(x-4)\\\\&#10;y-2=x-4\\\\&#10;\boxed{p:~~y=x-2}

The product of two numbers is 20. If one of the numbers is 4/7 what is the other number?
TiliK225 [7]

Answer:

35

Step-by-step explanation:

1. Translate the question into an equation:

  • \frac{4}{7}x = 20

2. Multiply both sides by 7/4.

  • \frac{4}{7}x * \frac{7}{4} = 20 * \frac{7}{4}
  • x = \frac{140}{4}
  • x = 35

What is the answer to the following: (reference the photo for answer)
Artyom0805 [142]

Answer:

9

Step-by-step explanation:

To calculate c from the first right angle triangle,

C2 = 36 + 16

C = sqrt(52)

To calculate a from the bigger right angle triangle,

B2 + 52 = (a + 4)2

B2 - a2 = -36 + 8a

A2 + 36 = B2

Solving both by elimination,

A = 72/8

=9
