All real numbers except x=-7
Step-by-step explanation:
Since 
is a discontinuity in the rational function, this makes the denominator equal to 0.
55 miles per hour, to answer questions like these you need to calculate the time (T=D/R) for each individual portion of the trip, add the time together to get total time, and then divide the total distance by the total time in order to get the average velocity in mph.
Um I think the first one is non proportional and the 2nd one is proportional y is 5 times x the 5 might be a negative
Well if 49 is the area, and you get area by multiplying one side by another side, and its a square so the numbers are going to be the same, so you would be multiplying two of the same numbers. And two of the same numbers that equal 49 is 7.
