First, make 6 1/3 a improper fraction:
![6 \frac{1}{3}= \frac{19}{3}}](https://tex.z-dn.net/?f=6%20%5Cfrac%7B1%7D%7B3%7D%3D%20%5Cfrac%7B19%7D%7B3%7D%7D)
. Now we have 19/3*7/3:
![\frac{19}{3}* \frac{7}{3}= \frac{133}{9}](https://tex.z-dn.net/?f=%20%5Cfrac%7B19%7D%7B3%7D%2A%20%5Cfrac%7B7%7D%7B3%7D%3D%20%5Cfrac%7B133%7D%7B9%7D)
.
Answer: y < 1
<u>Step-by-step explanation:</u>
![\begin{array}{c|c||l}\underline{x; x-3}&\underline{y=-x-2}&\\-3&-(-3)-2=1&\text{approaching but not including 1}\\-2&-(-2)-2=0&\\-1&-(-1)-2=-1&\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bc%7Cc%7C%7Cl%7D%5Cunderline%7Bx%3B%20x%3C-3%7D%26%5Cunderline%7By%3D2x%2B2%7D%26%5C%5C-5%262%28-5%29%2B2%3D-8%26%5C%5C-4%262%28-4%29%2B2%3D-6%26%5C%5C-3%262%28-3%29%2B2%3D-4%26%5Ctext%7Bapproaching%20but%20not%20including%20-4%7D%5C%5C%26%26%26%5Cunderline%7Bx%3B%20x%3D-3%7D%26%5Cunderline%7B%5Cqquad%20y%3Dx%5Cqquad%7D%26%5C%5C-3%26-3%26%5C%5C%26%26%26%5C%5C%5Cunderline%7Bx%3B%20x%3E-3%7D%26%5Cunderline%7By%3D-x-2%7D%26%5C%5C-3%26-%28-3%29-2%3D1%26%5Ctext%7Bapproaching%20but%20not%20including%201%7D%5C%5C-2%26-%28-2%29-2%3D0%26%5C%5C-1%26-%28-1%29-2%3D-1%26%5Cend%7Barray%7D)
The first function has the range of y < -4
The second function has the range of y = -3
The third function has the range of y < 1
The largest y-value is 1 and the smallest y-value is -∞, therefore the range (y-values) are from -∞ to 1 → y < 1
The answer is 720 mph, since we make time the x and distance y. We use the slope formula (y2 - y1)/(x2 - x1)
(179-23)/(17-4)
156 miles/13 mins
12 miles per min
Since the answer is in hours instead of minutes, we multiply 12 by 60 to get 720 mph
