Which two linear equations represent perpendicular lines? select two choices?
denis23 [38]
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.

Find the vertex of this parabola.<br><br><br><br> y = -2x2 + 4x + 12
STatiana [176]
For this case we have the following equation:
 y = -2x ^ 2 + 4x + 12&#10;
 Deriving we have:
 y = -2x ^ 2 + 4x + 12&#10;&#10;y '= -4x + 4
 We match zero:
 -4x + 4 = 0&#10;
 We clear the value of x:
 4x = 4&#10;&#10;x = 4/4&#10;&#10;x = 1
 Then, we substitute the value of x in the equation of the parabola:
 y = -2 (1) ^ 2 + 4 (1) + 12&#10;&#10;y = -2 + 4 + 12&#10;&#10;y = 14
 Thus, the vertex of the parabola is the ordered pair:
 (x, y) = (1, 14)
 Answer:
 
The vertice is:
 
(x, y) = (1, 14)
