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

Answer:
A radical equation is an equation in which a variable is under a radical. To solve a radical equation: Isolate the radical expression involving the variable. If more than one radical expression involves the variable, then isolate one of them.
Step-by-step explanation:
PLS MAKE ME AS BRAINLIST
The question demands that we find a fraction of a given quantity.
The 'of ' means multiplication.
So the total distance of the journey was

But they walked ¼ of the whole journey. We are supposed to find




Hence they walked 3.25 miles.
The answer is 35 please rate me the brainlest answer
Answer:
y = - 1/3 +2
Step-by-step explanation:
✯Hello✯
↪ first we need to rearrange this so the answer is equal to Y
↪ -3x on both sides
↪ 9y =-3x+18
↪ then divide by 9 to get y on its own
↪ Then we can simplify the answer -3x+18/9 further so the 2nd option is the answer
