Answer:
2 miles per hour
Step-by-step explanation:
We use the distance formula. D = r * t
45/3 = 15 mph | Trip 1 |
44/4= 11mph | Trip 2 |
15-11 = 4 mph difference traveling upstream or downstream. Thus the speed of the current is 2 miles per hour.
Yes, I have an idea.
Take the (-4) and put it into the F(x) in place of the 'x'.
Try it and let us know if it works.
Answer:
C because the line doesn't touch the x axis
Step-by-step explanation:
The real and actual correct answer is B because x on both of the equations equal 0.5
Answer:
C) A =
Step-by-step explanation:
First, read through what the question is asking.
Now, read it again, but slowly and take in everything it is saying (Don't read into it too slowly, or else you will over-complicate the problem and get frustrated - told from experience :) )
Alright, 4 less than 3 times the width. So, lets rearrange this and give width a variable (w).
So, the length is equal to:
l = 3w - 4
and the width is equal to:
w = w
The area of a rectangle is A = l * w
Let's plug in the values.
A = (3w - 4) * w
Now, simplify:
A =
A = is your final answer.
I hope this helps!
