Answer:
1. We can see that salesperson's weekly income is the sum of her constant weekly salary ($760) and a commission which is variable and depends on her weekly sales.
So, if we say that y is her weekly income and x is her weekly sales, we can write this as:
y = 760 + 0.075x
Note that we had to change percentage to decimal number dividing it by 100.
2 Since for each value of x there is only one corresponding value of y, we can say that this is a function. For any value of x we input there is only one solution we get - that is the main feature of function and a way to tell if something is really a function.
Since this is a function, it can also be written as:
f(x) = 760 + 0.075x
3. Domain of a function is, basically, set of all values of x for which the function can work. That practically means that, since x is weekly sale, it can not be negative (one cannot make -$500 sale, for example). However, it is possible that she doesn't make a sale one week, making it possible for x to be 0. Also, the value of her sales doesn't have to be integer (it is quite possible that she makes $673.50 sale).
All this means that appropriate domain for this function are positive real numbers including 0.
Answer:20.571
Step-by-step explanation:
x:y = 21: 24=7:8
8x=7y
y=8x/7
When x=18
y=8*18/7
y=20.571
Answer:
the total area of the given figure.
Step-by-step explanation:
Length of the bigger rectangle = 13 ft
Breadth of the bigger rectangle = x
Area of the bigger rectangle = A = 13 ft × x
Length of the smaller rectangle = 5ft
Breadth of the smaller rectangle = y = 6 ft
Area of the smaller rectangle = a = 5ft × 6ft
from the figure :
x + y = 14
x = 14ft - 6 ft = 8 ft
Total area of the figure = A + a
the total area of the given figure.
Answer:
Step-by-step explanation:
a- y equals start fraction four over three end fraction x minus four
