F(x) is the function that represents a given equation. It is defined more specifically by rules or conditions to satisfy the whole formula/equation.

In this case, f(x) has an inverse proportion with x (e.g. f(x) = 1/x). The second parameter says that f(x) = -15 when x is 30. Given that condition, just look for the formula, among the choices, that will result to -15 when x = 30. The answer is:

D. f(x) = -450/x

This is just -450/30 = -15

K = {(-3, -3), (-4, -4), (-5, -5), (-6, -6)} Is K a function and why? No, there is a limited number of ordered pairs in this lis
marysya [2.9K]

Answer:

Yes, no two ordered pairs in this list has the same second element.

Step-by-step explanation:

The function is a relation that associates to different elements x_1 and x_2 different elements y_1 and y_2.

Given K = {(-3, -3), (-4, -4), (-5, -5), (-6, -6)}

So,

  • x_1=-3\rightarrow y_1=-3;
  • x_2=-4\rightarrow y_2=-4;
  • x_3=-5\rightarrow y_3=-5;
  • x_4=-6\rightarrow y_4=-6.

Since different x have different image points y, this relation is the function. The correct answer is "Yes, no two ordered pairs in this list has the same second element."

Question 3 of 14
kobusy [5.1K]

Answer:

\$84,000

Step-by-step explanation:

Remember that

6\%=6/100=0.06

we know that

The amount the salesman would earn in a year must be equal to the base salary multiplied by 12 (number of months in a year) plus 6% of the amount sold in merchandise in a year

so                                                

4,000(12)+0.06(600,000)=\$84,000

In the number 8.028 does one 8 have a value of 100 times the other 8 ?
nirvana33 [79]

Answer:

No, The 8 in the ones place of the decimal and the 8 in the thousands. Decimals go by variables of 10 if that makes sense

so hopping from the 8 in the ones place it would go 10, 100,1000.

Therefore the statement is false because the value between the eitghts is not 100 its 1000

The y intercept in the scatter plot means that at 0 years working, you will get paid $8 per hr. The y intercept can be represented by the ordered pair (0,8). The independent variable is the # of years and the dependent variable is pay per hour.

Hope this helped :)
