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.
As the x-values go to positive infinity, the function's values go to positive infinity.
Answer: h=6
Step-by-step explanation:
Answer:
The point value of a test item is more than 1.25 points and less than 1.5 points.
So the formula is y=mx+b
the answer is y=-1x or -x+3 in cleaner form
y=-1x+3
