Answer:
The answer is in the media.Good luck!
The answer is: (z - 6)(z + 15)
z² + 9z - 90 = z*z + 15z - 6z - 6*15 =
= (z*z + 15z) - (6z + 6*15) =
= z(z + 15) - 6(z + 15) =
= (z - 6)(z + 15)
Answer: add 1 to both sides
-1+r+1≥4+1
simplify
x≥5
Step-by-step explanation:
The unit rate is the slope. m = Δy/Δx
So you want the Δx (change in x) to be 1
