Mayra's monthly salary is $4,540 plus she earns an 8% commission on her sales each month. Mayra's sales for January were $30,000
lesantik [10]
Work out 8% of 30000

10% of 30000 is 3000

1% of 30000 is 300
2% of 30000 is 300x2=600

Therefore 10%-2%= 3000-600=2400

It therefore follows that Mayra earned 4540 + 2400 = 6940 for January

Which graph represents the piecewise-defined function?
kifflom [539]

Answer: The first option is correct.

Explanation:

The given piecewise function is,

y=\begin{cases}-\frac{4}{5}x-3 & \text{ if } x

From the piecewise function we can say that if x<0, then

f(x)=-\frac{4}{5}x-3

If x\geq2, then

f(x)=3x-10

Since the f(x) is defined for x<0 and x\geq2, therefore the function f(x) is not defined for 0\leq x.

In the graph 2, 3 and 4 for each value of x there exist a unique value of y, therefore the function is defined for all values of x, which is not true according to the given piecewise function.

Only in figure the value of y not exist when x lies between 0 to 2, including 0. It means the function is not defined for 0\leq x, hence the first option is correct.
