Find all the points, if any, where the graph of 12x-5y=0 intersects (x+12)^2+(y-5)^2=169.
WITCHER [35]
I: 12x-5y=0
II:(x+12)^2+(y-5)^2=169

with I:
12x=5y
x=(5/12)y
-> substitute x in II:
((5/12)y+12)^2+(y-5)^2=169
(25/144)y^2+10y+144+y^2-10y+25=169
(25/144)y^2+y^2+10y-10y+144+25=169
(25/144)y^2+y^2+144+25=169
(25/144)y^2+y^2+169=169
(25/144)y^2+y^2=0
y^2=0
y=0

insert into I:
12x=0
x=0

-> only intersection is at (0,0) = option B

PLEASE HELP I GIVE ALL MY POINTS PLZZZZ!!!!! Select the correct answer. Vector u has its initial point at (1, -12) and its termi
dimulka [17.4K]

Answer:

Vector u has u_x = (5 - 15) = -10, and u_y = -4 - 22 = -26, and its component form would be u = -10i - 26j.

If vector v is in the opposite direction: 10i + 26j

And if it is double in magnitude: v = 20i + 52j

Hope this helps you! Ask me anything if yu have any quistions!
