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
Answer:
A. 650 + 35w > 825 + 15w
Step-by-step explanation:
Molly = $650
Molly's weekly additions = $35
Lynn=$825
Lynn's weekly additions= $15
Let the number of weeks = w
inequality to determine how many weeks, w, it will take for Molly's savings to exceed Lynn's savings
Molly's savings
$650+ $35w
Lynn's savings
$825 + 15w
The inequality is
650 + 35w > 825 + 15w
The inequality above will show the number of weeks it will take for Molly's savings to be greater than Lynn's savings
Replace the x's values in the equation with 5.
f(5)= -16(x-4) + 225
= -16(1) + 225
= -16 + 225
= 209
The Answer is 209
