Step-by-step explanation:
The expression is:
We start by adding the two terms within parentheses:
Therefore
Now we multiply 
with 
, which gives 
, so
And finally, adding the two terms, we find
Answer:
Baxter drives at 57 kilometers per hour.
Step-by-step explanation:
In order to find the answer, you have to use the following formula to calculate the speed:
speed=distance/time
distance=399 km
time=7 hours
Now, you have to replace the values in the formula:
speed=399 km/7 hours
speed=57 km/hour
According to this, the answer is that Baxter drives at 57 kilometers per hour.
Answer:
p = -0.05m + 22
Step-by-step explanation:
As given in question,
The relation between the price and demand can be given by,
where is p is price and x is demand.
Since in order to sell 300 cards the price has to be fix at $7.
So,
7 = 300m+b <u> </u> (1)
And for every additional card they need to drop the price by $0.05.
So,
7-0.05 = 301m+b
=>6.95 = 301m + b<u> </u> (2)
Subtracting equation (1) from equation (2), we will have
6.95 - 7 = 301m - 300m
=>m = -0.05
By putting the value of m in equation (1), we get
7 = 300.(-0.05)+b
=> b = 22
So, the linear equation that show the relation between price and demand is given by
p = -0.05m + 22
