The restriction for this is that x ≠ 4. This is because 4 - 4 = 0, and you cannot divide by zero.
An alternative way of writing this (interval notation) is (-∞, 4)U(4, <span>∞).

Answer:
For linear equations we use:
p=mx+b ------ (1)
Now we have the following coordinates:
(x1,p1)= (1000,280) and (x2, p2)=(5000,400)
First we need slope (m)
m= 
= 
Now we will plug the value of m in the first equation

=> 
=> b = 250
Now plug into p=mx+b using only m=0.03 and b=250

When the unit price is $440, we can plug in 440 in for p;

=> 
=> 
=> x = 6333 refrigerators
The lowest price at which a refrigerator will be marketed, we can find this by plugging x = 0 in p=mx+b.

=> p = $250
Answer:
the answer is 75
Step-by-step explanation:in total there are 5 full baskets and each holds 15 apples so 15 x 5 =75 and that is your answer.
Answer:
22.5
Step-by-step explanation:
Hey there! first, we find 25% of 30 which equals 7.5 then we subtract 30 - 7.5 which is 22.5
