850.5 * 2
9*189.................................
Using the distance formula:-
Distance = square root [ (17 -7)^2 + (-6 - -12)^2 ]
= square root ( 136)
= 11.66 answer
The equation to solve this should be x+3x=60
Parallel lines has equal slopes. Hence slope of line = -1/2
equation of line is (y - y1) = -1/2(x - x1)
y - (-6) = -1/2(x - 4)
y + 6 = -1/2x + 2
y = -1/2x + 2 - 6
y = -1/2x - 4
2x-1=x^2
If you plug these two equations into a graphing calculator, like desmos.com, you can see that the two lines will intersect at (1, 1).
