You should have written like this
1 hour /16 = x hour /100
x=100/16=25/4=6.25
but it asks how many hours after first hour
6.25-1=5.25
-6 ≥ 10 - 8x Subtract 10 from both sides
-16 ≥ -8x Divide by -8 to both sides
x ≥ 2 your answer is c
Answer: (1+2a)^2 or (1+2a)(1+2a)
Step-by-step explanation:
Plug in x-values and see which one has an incorrect y value.
(x, y)
x=0; y=0+7=7; CORRECT
x=2; y=2+7=9; INCORRECT
x=9; y=9+7=16; CORRECT
x=12; y=12+7=19; CORRECT
The point that is not on the online is (9, 16).
