The graph below shows the solution to a system of inequalities:

solid line joining ordered pairs 0, 3.75 and 15, 0. shade the portion of the graph above the line in the first and second quadrant

which of the following inequalities is modeled by the graph?

x + 4y ≥ 15; y ≥ 0
x − 4y ≥ 15; y ≥ 0
x + 4y ≤ 15; y ≥ 0
−x − 4y ≥ 15; y ≥ 0

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
