Answer:

D

Step-by-step explanation:

f^{-1}(x) means the inverse. The inverse is the function reflected over the y=x line. This means the values have been reversed. (x,y)-->(y,x). We are looking for a point that has reversed values from the table.

The table has (1.-5) so the inverse is (-5,1) or D.

Find x so that l || m. state the converse used.

Answer:

x = 12

Converse: Alternate Interior Angles Converse

Step-by-step explanation:

By the Alternate Interior Angles Converse, if (14x - 23) = (9x + 37), then l || m.

Use the equation to solve for x as follows:

14x - 23 = 9x + 37

Subtract 9x from each side

14x - 23 - 9x = 9x + 37 - 9x

5x - 23 = 37

Add 23 to both sides

5x - 23 + 23 = 37 + 23

5x = 60

Divide both sides by 5

\frac{5x}{5} = \frac{60}{5}

x = 12

saw5 [17]

Answer:

17:14 or 17 to 14

Step-by-step explanation:

since you know there are 14 girls, subtract 14 from 31 and then you'll get 17. since its asking for a ratio of boys to girls not girls to boys, you put boys first, then girls. so your answer will be 17:14
