II (THE Second one )
Step-by-step explanation:
Because when you substitute X by (-2)
you will get :
y=(-2)^2 - 6(-2) - 16 = Zero
So, -2 is not including in the interval .
He currently does 8, and is increasing by 2, so our equation will be
2x+8=30
Subtract the 8 over
2x=22
Divide by 2 on both sides
X=11
It will take 11 days
Answer:
y = 2x - 1
Step-by-step explanation:
y2 - y1 / x2 - x1
-5 - (-3) / -2 - (-1)
-2/-1
= 2
y = 2x + b
-3 = 2(-1) + b
-3 = -2 + b
-1 = b
