Answer:
y=0
Step-by-step explanation:
The equation for the slope is
m = ( y2-y1)/(x2-x1)
-2 = (4-y)/(1-3)
-2 = (4-y)/-2
Multiply each side by -2
4 = 4-y
Subtract 4 from each side
4-4 = 4-y-4
0 = -y
0=y
Answer:
Write and solve an equation of ratios:
16 miles 20 min
----------- = -----------
12 miles x
Then 16x = 240, and x = 240/16 = 15.
It will take 15 minutes to travel 12 miles.
(x^2+1)(x+2)(x −2)
*ps the ^ means it’s a exponent
Hope I helped <3 sorry if I was wrong :(
Answer:

Step-by-step explanation:
The directrix y=-6 is parallel to the x axes, so parabola has equation of the form

where
is the vertex of parabola and p is parabola's parameter.
By the definition,
is the distance from the vertex to the directrix, so

Hence, the equation of parabola is

See attached diagram for the graph of parabola and its directrix.
In vertex form this equation is

Step-by-step explanation:
x -0.1x = x(1-0.1) = 0.9x
