Answer: the expression for the combined total number of miles she biked in the two days is
117 - 5x miles
Step-by-step explanation:
Let x be the number of hours she biked yesterday.
In the two days, she biked for a combined total time of 9 hours. This means that the number of hours that she biked today is (9 - x) hours.
Distance = speed × time
Yesterday, Carmen went on a bike ride. Her average speed was 8 miles per hour. This means that the distance that she covered yesterday is 8x miles
Today, she went on another ride, this time averaging 13 miles per hour. This means that the distance that she covered today is 13(9 -x) miles.
An expression for the combined total number of miles she biked in the two days is
8x + 13(9 - x)
= 8x + 117 - 13x
= 117 - 5x
Answer:
The Earth making one revolution about the Sun.
Step-by-step explanation:
Answer: -127
Step-by-step explanation:
They are giving you the corresponding x value for which you should plug into the function. So plug 4 into g(x) and plug 4 into f(x). Then subtract them
g(x) = -3(4) + 4 = -8
Im assuming that is 
f(x) = 8(4)^2 - 9 = 119
Now do -8 - 119 to get -127
