-2x + 12 < - 4......subtract 12 from both sides
-2x + 12 - 12 < -4 - 12....simplify
-2x < -16...divide both sides by -2, changing the inequality sign
(-2/-2)x > -16/-2....simplify
x > 8

Step-by-step explanation:
0 = x² - 36
=> x² = 36
=> x = √36
=> x = 6

Answer:x^3+y^3+x^2 y+y^2 x-xy
Step-by-step explanation:
X+y(x^2 +y^2)- X y
Expand the bracket
X^3 +xy^2 +yx^2 -xy
Answer:
y = 100 - 2.5 x is the equation that represents her total profit from
