Answer:
As per the statement:
One bread recipe calls for 2 1/3 cup of flour another bread recipe called for to 1/2 cup of flour .
First we calculate how much flour the two recipes combine call for, by adding the amount of flour needed for both the recipes:
⇒
⇒
Tim would use cup of flour for two recipe.
We have to find how much flour will he have left over.
Tim has 5 cup of flour.
Subtract 17/6 from 5
Therefore, Tim would have left over.
Answer:
Domain is (0,∞)
Range is (45, ∞)
Step-by-step explanation:
Let x represents the number of persons and f(x) represents the average cost per person,
∵ Fixed cost = $ 2500
Also, additional cost is $ 45 per person,
So, the total cost for x persons ( in dollars ) = fixed deposit + additional cost for x persons,
= 2500 + 45x
Which is a rational function,
∵ A rational function is defined for all real numbers except those for denominator = 0
Denominator of f(x) = x
So, f(x) is defined for all real numbers except x ≠ 0,
Now, the cost can not be negative,
⇒ x > 0
Hence, the domain for f(x) is (0, ∞)
Again,
If
So, 45 < f(x) < ∞
i.e., range of f(x) is (45, ∞)
