X intercept=(1,0) Y intercept=(0,-2) You get x by substituting 0 for y and you get y by substituting 0 for x therefore to find y coordinates, 2(0)-2=y 0-2=y -2=y so (0,-2) And to find x coordinates, 2x-2=0 2x=2 2x/2=2/2 X=1 so (1, 0)
The answer <span>the third rope to counterbalance Sam and Charlie is F and vectF +vectF1 +vectF2 =vect0 let's consider axis y'y </span>vectF = -F vectF 1= F1cos60 vectF 2= F2cos45 -F = -F1cos60-F2co45 so F= F1cos60+F2co45= 350x0.5+400x0.7=457.84 pounds
