The answer is B since (5/9)^8 = 5^8/9^8
The rate of change is for every 1 week it looses 6 feet of gas
Answer:
i believe the answer would be y= -x-4
Step-by-step explanation:
a line that is perpendicular, will have and opposite reciprocal slope, so:
the slope of the line y=x-4 is 1, and the reciprocal of 1 is also 1.
now take the opposite of it, which is -1.
so the perpendicular line equation would be y=-x-4
i hope this helps :D
Answer:
Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
Find the domain of g(y), and this will be the range of f(x).
If you can't seem to solve for x, then try graphing the function to find the range.
Do a proportion
40/100= 8/x
8 x 100= 800
Cross multiply and divide
800 divided by 40= 20
So answer is 20
