Formula: Y=kx or y=ax or Y/x=a
K=12 k is also the slope!
Slope=12
Y=6
So If you plug in these values you get:
6=12x
Answer:
X=0.5 or 1/5
1 m=1000cm, so 21m=2100cm
1min=60sec
so 21 m/min=2100сm/60sec=35cm/sec
Answer:
The standard equation is y=ax^2+bx+k and the vertex way is y=a(x-h)(x-h)+x
so the coordinate for x is -b/2a, for your problem a=-4 b=-16 so the coordinate for x is -(-16)/(2*(-4))=-2. Now you have to replace x=-2 in your equation y=-4(-2)^2-16(-2)-11= 5.
The vertex is (-2, 5)
