Answer:
The coordinates of H’ is (-1,-6)
Step-by-step explanation:
Here, we want go get clockwise rotation about the origin
mathematically, if we had this kind of rotation, it would be that
(x,y) will turn to (y,-x)
So we have it that (6,-1 becomes)
(-1,-6)
Answer:
Step-by-step explanation:
Let the time taken by the john to get to his uncle be x.
Let the time taken by the john to get back from his uncle be y.
So,
x+y=12 ------ equation 1
According to the given velocities:
20x=30y
x=3/2y
Put the value x=3/2y in equation 1
3/2y+y =12
3y+2y/2=12
3y+2y=12*2
5y=24
y=24/5
y=4.8h
Now put the value of y in x=3/2y
x=3/2*4.8
x=14.4/2
x=7.2h ....
Answer:
y = -2x -8
Step-by-step explanation:
The equation for a line can be written in slope intercept form
y =mx+b where m is the slope and b is the y intercept
the slope is -2 and the y intercept is -8
y = -2x -8
