I believe it is answer A...He pays 485 originally and then 25 to his brother ever hour so 485+75 is 560 making A the answer.
If the y-intercepts are the same, the two equations represent the same line and there are INFINITELY MANY SOLUTIONS
Answer:
answer is 35
Step-by-step explanation:
The direction vector of the line
L: x=1+t, y=4t, z=2-3t
is <1,4,-3>
which is also the required normal vector of the plane.
Since the plane passes through point (-5,9,10), the required plane is :
Π 1(x-(-5)+4(y-9)-3(z-10)=0
=>
Π x+4y-3z=1
120 degrees or 0.67 radians
