Find the point that maximizes the objective functions P=2x+5y using constraints: y>=10-2x
y<=7-1/2x
x>=0
y>=0

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees

a mantle plume is an upwelling of abnormally hot rock within the earth's mantle. as the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.
