Answer:
y = -1/2x + 17/2
Explanation:
y = 2x + 1 is in slope intercept form
in the equation y = mx+b, m is the slope, and in the equation m =2
the slope of a perpendicular line is the negative reciprocal of the other slope.
slope of perpendicular= -1/m = -1/2
y = -1/2x + b
now find b by substituting in (1,8) into the partial equation
8 = -1/2 + b
b = 8+ 1/2
b = 17/2
please give thanks :) hope this helps
In centre is the centre of a circle that is inscribed in a triangle, called the incircle, i.e. circle is tangent to all three sides AND located inside the triangle. An incircle is roughly sketched in the accompanying diagram.
Since all radii of an incircle are equal, we have
4x-1=6x-5
Solving for x,
6x-4x=5-1
x=2
consequently, distance from incentre to each side of the triangle is
4(2)-1=7
check 6x-5=6(2)-5=7... checks.
Answers:
The value of x = 2
The distance from incentre to side of triangle is 7
