Answer:
B) 4 tablespoons of salt
Step-by-step explanation:
Here is the correct question: Scott used 1/3 tablespoons of salt to make 1/4 liters of beans. If Scott's recipe is for 1 liter of beans, how much salt will he need to make triple the recipe?
Given is the ratio of salt and beans to make recipe for 1 liter of beans.
Ratio given for 1 liters of beans;
.
Now, simplifying the ratio

∴ Ratio for salt and bean in a recipe for 1 liter of beans is
.
Next, finding the proportion of salt to make triple the recipe.
Triple the recipe means 3 times of 1 liter of beans, which is 3 liters of beans.
∴ The proportion of salt in 3 liter beans= 
Hence, 4 tablespoon of salt is required to make 3 liters of beans or triple the recipe.

Answer: f(x) = 4 if -1 ≤x ≤ 1
f(x) = x - 1 if 3≤ x ≤ 5
Step-by-step explanation:
if -1 ≤x ≤ 1
We can see that in this range the function is constant, f(x) = 4
if 3≤ x ≤ 5
In this region we can see a linear relationship, with the points (3, 2) and (5, 4)
as the extremes, we can find the slope of this linear equation as:
s = (4 - 2)/(5 - 3) = 2/2 = 1
So our equation is
f(x) = 1*x + b
to find the value of b we can evaluate our function in the first point, we know that when x = 3, y = 2, so we have:
2 = 1*3 + b
b = 2- 3 = -1
then f(x) = 1*x - 1
Then we have:
f(x) = 4 if -1 ≤x ≤ 1
f(x) = x - 1 if 3≤ x ≤ 5
