Answer:

Step-by-step explanation:

x2-12x-10

 -10    +    1    =    -9  

     -5    +    2    =    -3  

     -2    +    5    =    3  

     -1    +    10    =    9  

No two such factors can be found !!

x2 - 12x - 10  = 0

2.1      Find the Vertex of   y = x2-12x-10

Write an equation of the line that passes through (2 , 0) and is perpendicular to the line y=-1/7x-3
aleksley [76]

Answer:

y = 7x - 14

Step-by-step explanation:

If the given line has slope -1/7, then any perpendicular line has the slope which is the negative reciprocal of -1/7.  That is +7.

Apply the slope-intercept formula for the equation of a straight line, using 0 for y, 2 for x and searching for the y-intercept value b:

0 = 7(2) + b.  Then b = -14, and the desired equation is y = 7x - 14.
