Answer:
Step-by-step explanation:
we have
E------>the number of sit-ups
m----> the time in minutes
S----> the number of sit-ups after drinking the sports drink
----> equation A
----> equation B
substitute the equation A in the equation B
To find the answer, divide 7.2 miles by 3 hrs, this would get you to answer B, 2.4 miles per hour
W=wind
p + w=158...p=158-w
p-w=112...p=112+w
SO 158-w=112+w
46=2w
23=w
SO in conclusion you have the correct answer of wind being 23km/h while the plane is going 135 km/h

Answer:
i can't answer this but i can tell you this
The general form of an absolute value function is f(x)=a|x-h|+k. From this form, we can draw graphs.
y = a(x – h)2 + k, where (h, k) is the vertex. ... In the vertex form of the quadratic, the fact that (h, k) is the vertex makes sense if you think about it for a minute, and it's because the quantity "x – h" is squared, so its value is always zero or greater; being squared, it can never be negative.
Step-by-step explanation:
it is not the answer but i hope it helps:)
