Answer:
0 ≤x
Step-by-step explanation:
9x-3 ≤11x-3
Subtract 9x from each side
9x-9x-3 ≤11x-9x-3
-3 ≤2x-3
Add 3 to each side
-3+3 ≤2x
0 ≤2x
Divide by 2
0/2 ≤2x/2
0 ≤x
Answer:B
I think we are in the same class lol
Step-by-step explanation:448 divided by 14= 32
448 divided by 16= 28
B=speed of boat in water
Y= Speed of current
B+y=32
B-y=28
32 + 28 =60
60 divided by 2 = 30
32 -30 =2
B=30
Y=2

Answer:
f(t) = 5×0.87^t
Step-by-step explanation:
The general form for an exponential function described in this fashion is ...
... f(t) = (starting value) × (1 + (percent change))^t
Here, the "percent change" is -13%, or -0.13.
Then the value (1 + percent change) is (1 + (-0.13)) = 0.87. Putting this and the starting value into the form above, we have ...
... f(t) = 5 × 0.87^t
