Answer:
subtract
Step-by-step explanation:
A) The variable on the horizontal axis of the graph (the independent variable) is "pounds of rice". That is what the first number in the ordered pair (6, 18) represents.
The variable on the vertical axis of the graph (the dependent variable) is "total cost in dollars". That is what the second number in the ordered pair represents.
(6, 18) represents that the total cost of purchasing 6 lbs of rice is $18.
B) The unit price is found at the point where the independent variable has the value 1. That would be at the point (1, 3), which indicates the unit price is $3 per pound.
C) You would have to buy 4 lbs of rice for the total cost to be $12. There are at least two ways to find the answer.
- Draw a horizontal line on the graph at cost = $12. It intersects the graph at lbs = 4.
- Divide the total cost by the unit price. $12/($3/lb) = 4 lb.
Answer:
C. It represents the product of two rational numbers and its equivalent to a rational number.
Step-by-step explanation:
5 is a natural number, a real number and a rational number.
is a real number and a rational number.
The product of 5 × = 1.25 which is also a rational number in addition to being a real number.
Answer with explanation:
The given mathematical expression to solve : 
The prime factorization of each term can be written as follows :-
We can see that the greatest common factor of both the terms = 
So we rewrite the given expression as :-
By using distributive property :-
, we have
