I got you.
so lets plug in the values of the equation
y2 = 1
y1 = 5
x2 = 5
x1 = -2
soooo
which leaves you with
-4/7
1/3(-5x - 3) < 14
-5/3 x - 1 < 14
-5/3 x < 15
-5 x < 45
-x < 9
x > 9
Answer: x³+y³=180
Step-by-step explain: let's remember the formula x³+y³=(x+y)(x²-xy+y²) and also x³+y³=(x+y)³-3xy(x+y) then
