X-7y=10 and 2x+14y=21 is it parallel, perpendicular or neither and why

Not perpendicular and not parallel.

Step-by-step explanation:

The equations are not perpendicular because the slopes of the two lines are not negative reciprocals.

The equations are not parallel because the slopes of the two lines are not equal.

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
