Which of the following scenarios exhibits a function relation? Take the first set listed to be the domain of the relation.the set of tree heights and the set of trees in a forest
the set of car make and models and the set of people in a certain town
the set of birthdays and the set of students in a class
the set of people with Social Security cards and the set of Social Security numbers

Answers

Answer 1

Answer:

The scenario that exhibits a function relation is:

The set of people with Social Security cards and the set of Social Security numbers.

Step-by-step explanation:

We know that a function is a relation in which each element of first set has one image i.e. an element can't be mapped to two distinct elements of the other set.

The set of tree heights and the set of trees in a forest.

This relation is not a function.

Since, two trees may have a same height.

The set of car make and models and the set of people in a certain town.

This relation is also not a function.

Since, two people may have a car of same model.

The set of birthdays and the set of students in a class

This relation is not a function since two students may share same birthday.

The set of people with Social Security cards and the set of Social Security numbers.

This relation is a function.

Since, the security card number has a unique number on each car.

This means that each person has a unique card number.

Answer 2

Answer: The set of people with social security cards and the set of social cecurity numbers

Carl is boarding a plane. He has 2 checked bags of equal weight and a backpack that weighs 4kg. The total weight of Carl's baggage is 35kg. Write an equation to find the weight of the checked bags.

Answers

x=weight of one checked bag.
we can suggest this equation:

2x+4=35

Now, we solve this equation:
2x+4=35
2x=35-4
2x=31
x=31/2
x=15.5

Answer: the equation will be: 2x+4=35, and the weight of one checked bag will be 15.5 g,

Answer:

15.5

Step-by-step explanation:

2w+ 4 = 35 is the equation

15.5 is the total for w

The figures shown are similar.What is the scale factor?

A.

B.
1/4

C.
3/4

D.
1/6

Answers

Well first off here we know that one of the figures here is 24 and the other one is 18 so immediatly we can make a fraction out of this by putting the bigger number on the bottom as the denominator and the smaller number on the top as the numerator like so 18/24 we also know that this fraction can easily be simplified like so 3/4 (because 6 goes into each of them evenly) so the scale factor of these 2 figures is 3/4 or C.Enjoy!=)

HELP!!!Find the exact circumference of a circle with the given radius.

36 inches

C =

A) 72π in.

B) 36π in.

C) 18π in.

Answers

Hello!

To find the circumference of a circle, use the formula: C = 2πr. Since the radius is given, we can substitute that into the formula.

C = 2(36)π

C = 72π

Therefore, the circumference of the circle is 72π inches.

The system of equations below has exactly one (x, y) pair for its solution.4x+6y=244x+6y=24
2x+y=82x+y=8
If we double each side of the second equation, 2x+y=82x+y=8, we have 4x+2y=164x+2y=16. Explain why the same pair that is the solution to the system is also a solution to this new equation.
If needed, you can support your explanation with hanger diagrams (upload a picture), or by inventing a situation that the equations represent.
If we add the two equations in the original system, we have 6x+7y=326x+7y=32. Explain why the same (x, y) pair is also a solution to this equation.
Again, you can support your explanation with diagrams or a situation, if needed.

Answers

Final answer:

The equations are a system of linear equations. Modifying them through multiplication or addition while keeping both sides balanced doesn't change the solution. Any pair (x,y) satisfying one equation will satisfy the others.

Explanation:

In mathematics, these equations are a system of linear equations. This is essentially a set of two or more equations, with a common set of variables. The same pair (x, y) are the solutions for all equations, as the second equation is a simplified, scalar multiple of the first.

So, for the first original equation (4x + 6y = 24), and the modified one (4x + 2y=16) which is the second equation of the system doubled, we can see that the multiplier is the same for both the 'x' and 'y' on the left side, and the right side of the equation. Therefore, if a pair (x,y) has been found to satisfy the first equation, it will also work for the second, as essentially, the equations are equivalent.

Similarly, adding the original system of equations, we get 6x + 7y = 32. This also has the same solution set, just expressed differently. As long as you're performing the same operation (like doubling, adding etc.) to each side of the equations, the balance remains constant, retaining the same solution.
