Answer:
Step-by-step explanation:
(x)7 steak(dependent variable) = $44.10
(y)11 steak(independant variable)=$69.30
y=kx
11/7=1.57142857143
reduce that to 3 decimal spaces
y=1.57x
y=1.57(7)
11=1.57(7)
or
cross multiply 
7 × $69.30 and 11 × $44.10
and get 485.1 for both
Answer:
12.5%
Step-by-step explanation:
what I done was subtract 120 from 144 which will leave 24 then I find the percentage.
This makes it 3/24. When you divide the fraction out, you get 0.125. To turn that into a percentage, you simply multiply by 100. 0.125*100=12.5% you can check this by taking 12.5% of 24, which will give you an answer of 3
Factor out he common term, which in this case is "v"
So your answer would be v(9-1)
The weather in the three areas were all very similar on that day in particular.

Coordinates switch, and the new y-coordinate changes sign
Explanation:
We have point A with the coordinates (-1,2), when we rotate it c90º it becomes (2,1).
What happened? The coordinates switched and the x-coordinate of A (-1) became the y-coordinate of A' (1) and it changed its sign.
