Answer:
The relationships are correct and valid
Step-by-step explanation:
The correct question is as follows;
Verify the following
i.[ -3/4]^3 = -27/64
ii. [-2/3]^6 = 64/ 729
We have the solution as follows;
i) we have;
(-3/4)^3
That means ;
-3^3 = -3^3 = -27
4^3 = 64
so;
(-3/4)^3 = -27/64
ii) (-2/3)^6
(-2)^6 = 64
3^6 = 729
Thus;
(-2/3)^6 = 64/729
Let y directly proportional to X
thus y = CX
where c is proportionality constant
given c= 9
thus y = 9x
The slope of the line is 50. You can try looking at the equation, which is
y=50x+500
500 is your y-intercept, and is where the cost starts.
50 is your slope, since the cost goes up by $50 every time.
x is how many hours, which determines how many $50s there are.
I hope this helps. All in all, the slope is 50.

$152 - $22.80 = $129.20
The cost of the coat would be $129.20
