The Johnson farm has 500 acres of land allotted for cultivating corn and wheat. The cost of cultivating corn and wheat is $42 and $30 per acre. Jacob Johnson has $17,400 available for cultivating these crops. If he wishes to use all the allotted Lynn and his entire budget for cultivating these two crops, how many acres of each crop should he plant?

b or 2, just plug these equations into your graphing calculator then check the graph to see the image. if it matches up then that's your answer!

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
