Which characteristics will prove that ΔDEF is a right, isosceles triangle? segment DE is larger than segment EF, and their slopes are the same. segment DE is larger than segment EF, and their slopes are opposite reciprocals. The lengths of segment DE and segment EF are congruent, and their slopes are the same. The lengths of segment DE and segment EF are congruent, and their slopes are opposite reciprocals.

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

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
