X + 15 = 5X -2
15 + 2 = 5X - X
17 = 4X
17/4 = X
4.25 = X
i. 5x ≥ -12 (It can be solved similarly to an equality)
5x/5 ≥ -12/5
x ≥ -12/5
The number line looks along the lines of
<---------l-------------> (filled circle)
-12/5
ii. The smallest integer that satisfies x ≥ -12/5 is -2 because -12/5 = -2.4.

Answer:
3i √3
Step-by-step explanation:
you can't have the square root of a negative number
so we use "i"
Answer:
-2y(y + 4)
Step-by-step explanation:
-10y^2 - 3y - (5y - 8y^2)
= -10y^2 - 3y - 5y + 8y^2
= -2y^2 - 8y
= -2y(y + 4)
