Fred. .9 is larger than .6 therefore, Fred walked a longer distance.
If you only want to know what it means ¨c¨ then it is the Denominator, cause you are referring a fraction.
The vertex is when x=0, so (0, 2) is the answer.
The area of the wall is 92,322
Money to be spent per day <$100
To rent a car:
Minimum amount per day= $45
Amount per mile= $0.25
Hence amount spent depends on distance travelled.
If distance travelled= x; fee for travel= 0.25x
Hence finally we need the fare to be less than $100
And fare is $45+0.25x
So the final inequality is 0.25x+45<100.
Hope it helps.
