Answer:
y=- x+
x+
Step-by-step explanation:
First, calculate the slope of the line that is perpendicular to the equation of line we are asked to find
m=(y2-y1)/(x2-x1)
   =(2-(-4))/(-2-1)
   =6/-3
   =-2
in this equation the slope is 2, and to find the first equation, use y=mx+b
use the point (1, -4) to find b
-4=(2)(1)+b
-4=2+b
b=-6
the first equation of the line is y=2x-6
to find the x intercept of that line substitute 0 for y
0=2x-6
2x=6
x=3
the slope of a line perpendicular to this would be the opposite reciprocal of the slope which would be equal to -1/2
for the second equation of the line to pass thorugh the x-intercept of the first line, it must pass through (3, 0), so substitute and solve for b
y=mx+b
0=(-1/2)(3)+b
b=3/2
thus the equation of the line that is perpendicular to the line through (1,-4) and (-2, 2) and passes through the x intercept of that line is y=- x+3/2
x+3/2
 
        
             
        
        
        
the answer is 16.5cm 
just add 15 +1.5 and you get 16.5

Answer:
AC ≈ 9,7sm
Step-by-step explanation:
AB=7  One side of a right triangle
BC=12  Hypotenuse of a right triangle
AC=?=x  The other side of a right triangle
x²+7²=12²  
x²=144-49
x²=95
x=√(95) ≈ 9,7
AC ≈ 9,7sm
