The answer is: f(19)=-3\frac{6}{7}

<em><u>Explanation</u></em>

Given function is:   f(x)= \frac{3}{x+2}-\sqrt{x-3}

For finding the value of f(19), we just need to <u>plug x=19 into both sides of the above function and then simplify the right side</u>. So.....

f(19)=\frac{3}{19+2}-\sqrt{19-3}\\ \\ f(19)=\frac{3}{21}-\sqrt{16}\\ \\ f(19)=\frac{1}{7}-4\\ \\ f(19)= \frac{1-28}{7}=-\frac{27}{7}=-3\frac{6}{7}

So, the value of f(19) will be -3\frac{6}{7}

She would earn $49.70 per day because $248.50 divided by the number of days (5) would equal $49.70 per day. You can check your work by working backwards. If she earned $49.70 each day for 5 days, she would have $248.50.

soldier1979 [14.2K]
If y varies inversely with x, then we know that:

y = k/x

We are given x and y, so plug in the numbers and solve for k.

1.5 = k/6.4

k = 1.5*6.4

k = 9.6

Identify the interval that is not equal to the other three. Explain your reasoning. (Intervals are 15-19; 30-34; 40-45; 45-49)
ahrayia [7]
40-45 isn't equal to the other three, because the other intervals increase by 4, but 40-45 increases by 5.
