Answer:
we need more information then that....
Step-by-step explanation:
In order for two linear lines to be perpendicular, the product of their gradient must be -1.
Let's take y = x + b and y = -x + b
This is already in the form: y = mx + b, where m is 1 and -1 respectively.
Since the product of their gradient is -1, they are said to be perpendicular.
For this case we have the following equation:

Deriving we have:

We match zero:

We clear the value of x:

Then, we substitute the value of x in the equation of the parabola:

Thus, the vertex of the parabola is the ordered pair:
Answer:
The vertice is:
70 cm
ex:
100 cm in a meter
so you’d do 100-30 cm
and that equals 70 centimeters
Answer:
(-6,-4)
Step-by-step explanation:
A reflection over the x-axis changes the y variable
(x,y)--->(x,-y)
