Step-by-step explanation:
1/2(4-14y)=y+50
1/(8 - 28y) = y + 50
8y - 400 - 28y² +
Now you can solve
No, they forgot to switch variable labels after solving for the independent variable...
y=-8x+4
y-4=-8x
(y-4)/-8=x
Now that you have solved for the independent variable x, you switch the variable labels...
y=(x-4)/-8
f^-1(x)=(x-4)/-8 which should really be rewritten as:
f^-1(x)=(4-x)/8 :P
inches of snow is left
<em><u>Solution:</u></em>
Given that,
From given,
<em><u>how many inches of snow is left</u></em>
Snow left = original amount of snow - sun melted
Thus inches of snow is left
Answer: A x=1/4y^2
Step-by-step explanation:
Because to make sure on the graph is counterclockwise for the vertex for the starting point.
80p=pr^2+p(2r)^2
80p=pr^2+4pr^2
80=r^2+4r^2
80=5r^2
16=r^2
r=4 for the smaller circle´s radius, and 8 is the larger circle´s radius.
Have a nice day, I hope this was helpful :D
