Step-by-step explanation: The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!
Answer:
See below.
Step-by-step explanation:
The corners of the square are:
(-7, 6) which becomes (-6, 7)
(-2, 6) which becomes (-6, 2)
(-7, 1) which becomes (-1, 7)
(-2, 1) which becomes (-1, 2)
From the top left corner of the square, ABCD rotates to ACDB (clockwise), so Darla is correct.
The new square is in the same quadrant as the original, so quadrant 2.
Answer:
Let b = rate of the boat.
Let r = rate of the river.
The rate going downstream is b + r.
The rate going upstream is b - r.
rate x time = distance
4(b + r) = 144 ---> b + r = 36 [divide both sides by 4]
9(b - r) = 144 ---> b - r = 16 [divide both sides by 9]
Add town: 2b = 52
Divide by : b = 26 mi/hr
r = 10 mi/hr

Answer:
The required constant of variation is 4 and the equation is y=4xz over w (over meaning a fraction)
I don't know if you need a explanation on how to do this, just let me know if so.
