Read Solution (Total 3)
-
- x-intercept=(a,0,0) let
so value of a=72/6
=12
z-intercept=(0,0,b) let
value of b=72/(-3)
=-24
applying Pythagoras theorem:
distance between x- and z-intercept=sqrt[sqr(12)+sqr(24)]
=sqrt(144+576)

- let the equation : ax+by+cz=k
if x-intercept put y=0 & z=0
if y-intercept put y=0 & x=0
if z-intercept put y=0 & x=0
now for this question: x=72/6=12
z=72/-3=-24
y=72/8=9
distance=sqrt((x^2)+(z^2))=sqrt(144+576)=26.832

- given 6x+8y-3z=72.dividing both sides by 72 we have (x/12)+(y/9)-(z/24)=1.
So x-intercept=12 and z-intercept=24.differnce is 12 - 13 years agoHelpfull: Yes(1) No(9)
