Hope that helps :)
Answer:
A.
Step-by-step explanation:
Rise over Run
There are 16 cups in a gallon. You have 2 gallons to begin with, so you have 32 cups to begin.
You give out 20 cups, so you only have 32-20 cups left. 32-20=12. You have 12 cups left.
Answer:
a)<em> k(x) = 5x - 2</em>
x = 5(y) - 2
5y = x + 2
y = (x+2)/5
<u>k-¹(x) = (x+2)/5</u>
b) <em>h</em><em>(</em><em>x</em><em>)</em><em> </em><em>=</em><em> </em><em>(</em><em>x</em><em>+</em><em>1</em><em>0</em><em>)</em><em>/</em><em>(</em><em>x</em><em>-</em><em>3</em><em>)</em><em> </em>
x = (y+10)/(y-3)
x(y-3) = y + 10
xy -3x = y + 10
xy - y = 3x + 10
y(x-1) = 3x + 10
y = (3x + 10)/(x-1)
<u>h-¹(x) = (3x+10)/(x-1)</u>
