(40,25.20)(72,21.36)
slope = (21.36 - 25.20) / (72 - 40) = -3.84 / 32 = -0.12
y = mx + b
slope(m) = -0.12
(40,25.20)...x = 40 and y = 25.20
sub and solve for b, the y int
25.20 = -0.12(40) + b
25.20 = - 4.8 + b
25.20 + 4.8 = b
30 = b
ur equation is : y = -0.12x + 30....where x is ur minutes, and y is remaining credit.
after 86 minutes...
y = -0.12(86) + 30
y = - 10.32 + 30
y = 19.68 <===
The answer is no because after each 3 there is one more zero added
to be repeating the number of zeros would have to stay the same
I think you are right so far what i've done comes out to your answer.
Answer:

Step-by-step explanation:
Answer:
19530 meters
Step-by-step explanation:
There are 7 days per week. If audrina swims 21 times for 0.93 km each day, we can multiply 0.93 km by 21 as we add 21 instances of 0.93. Our answer, using a calculator, is 19.53 km. Multiplying that by 1000, as there are 1000 meters per kilometer, we get 19530 meters as our answer
