Answer:
Input is the value of w and the function f = 24/w as length x breadth = area of rectangle
If w = 0.5, then f = 24/0.5 = 48cm. So, it is a possible input of the function.
If w = 48, then f = 24/48 = 0.5cm. So, it is a possible input of the function.
If w = 0, then f = 24/0 = 0cm. So, it is not a possible input of the function as it cannot be defined
If w = -6, then f = 24/-6= -4cm. So, it is not a possible input of the function as a length and width can't be negative
If w = 3, then f = 24/3 = 8cm. So, it is a possible input of the function.
Answer:
24 blue cars
Step-by-step explanation:
Set up a proportion to solve this...
40/5 = x/3 (forty red cars is to five red cars as 'x' number of blue cars is to 3 blue cars)
Now solve by cross multiplying...
120 = 5x
24 = x
for the columns where is less than or equal zero, use the first line of the function to calculate the value of f(x)
for every x greater than zero, use the second line to determine the value
hope this helps and gives some insight what to do.

have a beautiful day

Answer: B (the lower one)
Step-by-step explanation:
First let's solve for y.
x + 2y = 4
2y = -x + 4
y = -1/2x + 2
It is B since the y intercept for that graph is 2.
