Answer:
2989
Step-by-step explanation:
Always start with the bracket
3000 + 9 = 3009
3009 - 20 = 2989
Answer:
y=-5
Step-by-step explanation:
The expression is (y-3)/(y+5).
Thus, value y=-5 is not permissible, because the denominator would be zero.
WE know that (distance) = Speed * time
and Speed = distance/time & time = distance/speed
Let AB = 60 mi. & the speed is 55 mi/h , then the spent to reach the rink is
t= 60/55 = 1.09 h
Since the total time is 2.75 h & he spent 1.09h to go to the rink, so the time spent on his way back is 2.75-1.09 = 1.659 h
So his speed on his way back is 60/1.659 =36.16 mi/h
Answer:
Step-by-step explanation:
The line can be written as
Since the line is contained in the plane, if we take any two points of this line they will lie in the plane.
Give values for t =0 and 1
We get two points (x,y,z) as (1,3,0) and (3,2,1)
Now we have another non collinearpoint (1,1,1) (given)
The plane equation can be written using these 3 points using the determinant.
x-x1 y-y1 z-z1
x2-x1 y2-y2 z2-z1
x3-x1 y3-y1 z3-z1 =0
Substitute the values form the points.
We get
Expand the determinant as
(x-1)(-1+2)-(y-3)(2-0)+z(-4-0) =0
x-1-2y+6-4z =0
x-2y-4z+5 =0
