Answer:
x = 5 , y = 15
Step-by-step explanation:
You can solve this using substitution.
Let the quantity of cheese wafers be denoted by x and the quantity of chocolate wafers denoted by y
2x + 1y = 25
x + y = 20
These two equations are the answer to part A, (remember to include the above prompt which says what x and y denote).
For part B I used substitution because it was more applicable to the question then addition or elimination.
ACTUAL WORK
Set 2x + 1y = 25 equal to x
x = 25 - y / 2
Replace x with y in the second equation
(25 - y / 2) + y = 20
And solve for y
y = 15
Since we know what y is we can replace y in the second equation and find what x is
x + 15 = 20
Solve for x
x = 5
A) is 0.83 and idk how to do b)
Answer:
or 
Step-by-step explanation:
By definition the function
has a domain of 
.
Since the function is not defined for the values of x negative or equal to zero.
The range of this function is all the real numbers.
Since 
when 
and 
when 
In this case we have the function 
Therefore since the log function is squared then its range is now
