Answer:
Step-by-step explanation:
Let 
and 
be two rational numbers, where b and d are not zero and a, b, c and d are integers.
1. Given:
2. Multiply to get a common denominator :
3. Simplify:
4. Since 
then 
If 
are integers, then 
are integers too. So the fraction
is a rational number
There is a mandatory fixed rate of $ 35 that Raphael will have to pay once the service call has been made. This fixed rate is the constant.
The per hour rate is $20. Suppose the machine took "x" hours to get fixed. Then the variable part of the repair cost will be 
.
Thus, Repair Cost=Fixed Rate Cost+Variable Cost
Or, 
where 
is the total repair cost. Thus, if Raphael ‘s machine took 2 hour to fix, the repair cost is:
dollars.
Therefore, the last option is the correct option.
r are increasing and s are increasing, therefore the second graph or third graph. For r = 0 → s = 10.
Therefore your answer is second graph.
Answer:
Its all positive integers
Step-by-step explanation:
Answer:
$66,092.50
Step-by-step explanation:
In 1988, the car cost $17,000
Annual inflation over this period was 3.54% from 1988 to 2017
After adjusted for inflation, $17,000.00 in 1978 is equal to $66,092.50 in 2017
Therefore, the cost of that car in 2017 is closest to $66,092.50
