Answer:
Track 2
Step-by-step explanation:
180 degrees would turn the train completely around so if it entered on track 2 then it left on track 2
what is the equation of a line that is perpendicular to 8x+6y=-5 the answer is b
Answer:
7:21
Step-by-step explanation:
Lcm(9,12)=9*4=36 minutes later
That is
6:45+36min=7:21
I think that the interval that is always increasing is interval number 1.
Answer:
Right side towards positive x axis
Step-by-step explanation:
Let us see the basic rule to find the orientation of parabolas.
1. If power if x is 2 and y is 1 , the parabola opens up or down.
2. If the power of y is 2 and that of x is 1 , the parabola opens right or left.
3. If the coefficient of
in case 1 is negative it opens downward
4. If the coefficient of
in case 2 is negative , it opens left towards negative x axis.
Hence our equation is

here is satisfies the case 2. hence it opens right or left . Also the coefficient of
is positive so it opens up to the right side , that is towards positive x axis.
