Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
Area = 52.81 square inches
Step-by-step explanation:
Answer: the commission that she earns for selling each suit is $13
the commission that she earns for selling each pair of shoes is $8
Step-by-step explanation:
Let x represent the commission that she earns for selling each suit.
Let y represent the commission that she earns for selling each pair of shoes.
One week, she earned $47 in commission for selling 3 suits and a pair of shoes. It means that
3x + y = 47 - - - - - - - - - - 1
The next week, she earned $107 in commission for selling 7 suits and 2 pairs of shoes. It means that
7x + 2y = 107 - - - - -- - - - -2
Multiplying equation 1 by 2 and equation 2 by 1, it becomes
6x + 2y = 94
7x + 2y = 107
-x = -13
x = 13
Substituting x = -13 ,into equation 1, it becomes
3×13 + y = 47
39 +y = 47
y = 47 - 39 =
y = 8
Finding the extreme point :
Now,
f''( x ) at x = 1/3 and -1 is :
Therefore, it is maximum at x = -1 and minimum at x = 1/3 .
Hence, this is the required solution.
Answer:
x= 
Step-by-step explanation:
We have given,
We need to solve for x.
Squaring both sides, we get:
3-5x = x + 2
or 3 - 2 = x + 5x
or 1 = 6x
or x =
Hence we got x=
