Percent of change = (new value - old value)/(old value) * 100
percent of change = (6400 - 8700)/(8700) * 100
Step-by-step explanation:
x+2y ≥ 4 => y ≥ -½x +4
-2x + y > -3 => y > 2x - 3
The answer to that problem is 221.475
No.
This is because the y value of 1 repeats itself, which never happens in an exponential function. This function is likely quadratic, which forms a parabola.
-2x + 15y = -24
2x + 9y = 24
Adding to eliminate x:-
24y = 0
y = 0
Substitute for y in the first equation:-
-2x + 15(0) = -24
-2x = -24
x = -24/-2 = 12
Solution is x = 12 , y = 0
