Answer:
a. x + 4y = 160
b. 160
c. 40
Step-by-step explanation:
a. We can define the variables as ...
x = number of 1/2-liter bottles
y = number of 2-liter bottles
For the total number of liters to be 80, we require
1/2x + 2y = 80
We can multiply this by 2 to eliminate the fraction.
x + 4y = 160
__
b. The x-intercept is 160. It is the number of 1/2-liter bottles required when no 2-liter bottles are used.
__
c. The y-intercept is 40. It is the number of 2-liter bottles required when no 1/2-liter bottles are used.
An inverse function will simply reverse the coordinate pairs of the original function. If f(x)=(x,y), f^-(x)=(y,x).
So 18 is H
...
If f(x)=y=3x-4, to find the inverse function, solve for x, and then reverse the labels as seen below...
y=3x-4
y+4=3x
(y+4)/3=x so the inverse function is:
y=(x+4)/3

Answer:
$133
Step-by-step explanation:
Put 14 where t is in the formula and do the arithmetic.
c = -9.5×14
c = 133 . . . . cost in dollars
Sanjay paid $133 for the 14 t-shirts he bought.
