Answer:
i think it's -1 / -1
nut i'm not sure so if its wrong then sorry , and don't thank's me...
Answer:
a)
Step-by-step explanation:
hello,
because of the end behaviour the constant in 
should be positive so we have a) or d)
f(0)=-3 in both cases
for A) f(x)=
so f(x)=0 for 
so the correct answer is A)
hope this helps
A. T= d/r
A good way to remember this is by making a pyramid with 3 parts and putting distance at the top and rate and time in the other two parts. This way you can visibly see the equation and use it if you need to find one for rate.
B. It's reasonable to write distance as a positive number because distance is always positive. You are not able to have a negative distance. Imagine someone standing on a side walk. Even if they are not moving, their distance is 0 which is positive. If they move backwards or forwards, their distance is still positive because it is more than that 0 and they are gaining something.
C. Just plug in the numbers into the formula.
T= d/r
T= 32.12 m /<span>8.8 m/min
T= 3.65 min

Answer:
63 m
Step-by-step explanation:
We are given the following in the question:
Average speed of swimming = 45 m/min
Time = 1 minute 24 seconds
Converting time into minutes:
Formula:
Putting values, we get.
Thus, Alex swims for 63 m in 1 minute and 24 seconds.
Answer:
The slope is -4
Step-by-step explanation:
the m part of y = mx + b is the slope.
