How are you able to use identity (math wise) in a real life scenario?

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

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

just sum

10 + 10 = 20

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
