Write the equation of the line that passes through the point (-1,7) and is perpendicular to the line x=4. explain how you determined this equation.

The answer is: y = 7

Step-by-step explanation:

For x = 4, it is a vertical line where everything is x = 4. No matter what y is, x always equals 4.

For the line y = 7, it is a horizontal line, perpendicular to the line x = 4. The line y = 7 passes through the point (-1, 7) and all other similar points where y = 7.

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

51

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
