Determine the quotient: 2 4/7 ÷ 1 3/6
Scilla [17]

First we must change these numbers to improper fractions:

2\frac{4}{7}=\frac{18}{7}

1\frac{3}{6}=\frac{9}{6}

So then we set it up:

\frac{18}{7} ÷ \frac{9}{6}

When we divide fractions like this, we must flip the second fraction and change the sign from division to multiplication like so:

\frac{18}{7}*\frac{6}{9}

Then we solve:

\frac{108}{63}

Then if we divide the numerator and the denominator by 9, we get:

\frac{12}{7} or, in mixed-number form, 1\frac{5}{7}.

Find the range of the graphed function
Illusion [34]

Answer:

Correct choice is A

Step-by-step explanation:

The range of the function are all possible values which variable y can take.

From the given diagram you can see that the variable x changes from -4 to the 9. So the domain of the function is -4\le x\le 9.

Also the variable y takes its values from -4 to 8. Thus, the range is -4\le y\le 8.
