Given segment AC and point B that lies on AC,
ololo11 [35]

The total length of the segment AC is the sum of AB and CB, which gives, CB = 9

<h3>How can the length of CB be found?</h3>

The given parameters are;

  • AC = 17
  • AB = 32 + 3•x
  • CB = 57 + 6•x

Required: <em>CB</em>

Solution:

AC = <em>AB + CB</em> by segment addition property

Therefore;

AC = 17 = 32 + 3•x + 57 + 6•x = 89 + 9•x

17 = 89 + 9•x

x =  \frac{17 - 89}{9}  =  - 8

CB = 57 + 6•x = 57 + 6 × (-8) = 9

Therefore;

  • <u>CB = 9</u>

the slope of line PQ is m= 1/4. find the equation of the line that is parallel to line PQ and that has the y intercept b= -3
nevsk [136]
For this case we have that the generic equation of the line is given by:
 y = mx + b&#10;
 Where,
 m: slope of the line
 b: intersection with the y axis.
 Since the line is parallel to PQ, then the slopes are equal.
 We have then:
 m = 1/4.&#10;
 On the other hand we have:
 b = -3&#10;
 Substituting values we have:
 y = (1/4) x - 3
 Answer:
 The equation of the line that is parallel to line PQ and that has the and intercept b = -3 is:
 y = (1/4) x - 3

mariarad [96]

Answer:

7 1/17 shifts

Step-by-step explanation:

That would be 7 1/2 divided by 1 1/16

=  15/2 / 17/16

= 15/2 * 16/17

= 15 * 8  /  17

=  120/17

= 7  1/17  shifts
