Answer:
a) 
b) The inverse function is a reflection of the original function across the line
y = x. For example, if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x. So you would use it to find the x-value at a y just like you use the original to find the y value at an x.
Step-by-step explanation:
To do an inverse of a function you first switch the independent variable (d) and the dependent variable (c).
d = 0.45c + 5.50
Then you solve for c
d - 5.50 = 0.45 c
c = (d-5.50)/0.45
48 points gained in those 3 days.
Subtract 220 with 48, then add 96. Last step would be subtracting 220 with the amount they have now in those 3 days to find how much points the stock market gained in those 3 days.
Subtract 220-48.It‘ll be 172.
Add 172 with 96. 172+96=268.
Subtract 268 with how much points the stock market had 3 days ago. 268-220.
Sot eh stock market gained 48 points in 3 days.
Zero
There is no solution for these equations as there is no even one point of intersection between them
Answer:


The maximum pounds of cheese that Ariana can buy is 8
Step-by-step explanation:
Let
x ---> the amount of cheese In pounds, that Ariana can buy
we know that
The cost of 3 loaves of bread plus the cost of the cheese must be less than or equal to $50
so
The inequality that represent this situation is


solve for x
subtract 10.08 both sides


divide by 4.99 both sides

Therefore
The maximum pounds of cheese that Ariana can buy is 8
