12a + 6 + 3a = 15a + 2
15a = 15a - 4
0 = - 4
Answer:
Yes it does show a dilation
To reflect it over the x axis, all y units get multiplied by -1, so we multiply the equation by -1. After that, to stretch it vertically, we multiply it by that factor, which is 2. Right now , we have -2log(5x). Lastly, we shift it down 3 units by subtracting 3 from the overall equation, resulting in -2log(5x)-3
1: B $3.85
2: C The rabbit; 14 miles per hour
3: C 2 1/2 miles
1. Reason: To find the price per gallon, all you need to do is divide 46.20 by 12 to get 3.85
2. Reason: To find which animal is faster all you have to do is subtract the greater number, which is the rabbit that travels 35 miles per hour from the smaller number which is the fox that travels 21 miles.
Subtract: 35-21= 14. So the rabbit is faster by 14 miles.
3. Reason: If Randy walks 1/2 mile in every 1/5 hour, to find the much he will walk in a hour you could count up:
1/2 mile = 1/5 hour
1 mile = 2/5 hour
1 1/2 mile = 3/5 hour
2 mile = 4/5 hour
2 1/2 mile = 1 hour
So, Randy will travel 2 1/2 miles in a hour.
