Is every relation also a function? Explain.
A. No. A relation is a special type of function where each input maps to exactly one output. In a function, an input can have one or more outputs.
B. Yes. A function is a special type of relation where each input maps to exactly one output. In a relation, an input can have one or more outputs.
C. Yes. A relation is a special type of function where each input maps to exactly one output. In a function, an input can have one or more outputs.
D. No. A function is a special type of relation where each input maps to exactly one output. In a relation, an input can have one or more outputs.
Answer:
I believe the answer is D.
Step-by-step explanation:
No. A function is a special type of relation where each input maps to exactly one output. In a relation, an input can have one or more outputs. Hence, option D is true.
Used the concept of definition of function which states that, A relation between a set of inputs having one output each is called a function.
Since the relation that defines the set of inputs to the set of outputs is called the relation. And, In function, each input in set X has exactly one output in set Y.
Hence, All functions are relations but all relations are not functions.
Therefore, the correct option is D,
D) No. A function is a special type of relation where each input maps to exactly one output. In a relation, an input can have one or more outputs.

which pints are solutions tot he equation y=11x?
select all that apply
(-9,99)
(11,144)
(3,33)
(-17,-187)
(3/11,3)
The solutions of the equation y = 11x are;
⇒ (3, 33)
⇒ (-17, -187)
⇒ (3/11, 3)
What is Equation of line?
The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The equation is,
y = 11x
Now,
The solutions of the equation is always satisfy the equation of line.
So, we check all the points as;
First point (x , y) = (- 9, 99)
Substitute in the equation, we get;
y = 11x
99 = 11 x - 9
99 ≠ - 99
Thus, This is not a solution.
Second point (x , y) = (11, 144)
Substitute in the equation, we get;
y = 11x
144 = 11 x 11
14 ≠ 121
Thus, This is not a solution.
Third point (x , y) = (3, 33)
Substitute in the equation, we get;
y = 11x
33 = 11 x 3
33 = 33
Thus, This is a solution.
Fourth point (x , y) = (- 17, - 187)
Substitute in the equation, we get;
y = 11x
- 187 = 11 x - 17
- 187 = - 187
Thus, This is a solution.
Fifth point (x , y) = (3/11, 3)
Substitute in the equation, we get;
y = 11x
3 = 11 x 3/11
3 = 3
Thus, This is a solution.
Therefore, The solutions of the equation y = 11x are;
⇒ (3, 33)
⇒ (-17, -187)
⇒ (3/11, 3)

Sorry if I'm wrong but...…..
I think the first one is an equation and it's a fraction with powers. (4 and 5).
The next one is a fraction and it is to the power of the number above you have to figure out if you have to multiply the powers with the number under it add them and divide or multiply them by the other number.
The third one is a multiplication problem you have to figure out what "r" is to figure it out you have to do 6 to the 2nd power to get r and you have to do 2 to the 6th power to get the other r. Then multiply the numbers together tp get the answer.

Step-by-step explanation:
12.) If one ticket is $9.50, and 879,575 tickets were sold, the two need to be multiplied. 9.5 * 879,575 = 8355962.50
So the total profit was $8,355,962.50
If each theater made an equal profit of that total, then just divide it by 755, but if that's not the case, then don't do that.
13.) If the boat can carry 582 passengers, and 13,105 people had ridden the first boat, then you have to divide the number of people riding the boat by the passenger count to determine the amount of trips made.
13,105 / 582 is 22.5, but you can round it to 23, because half of a trip isn't going to be made. I'm not entirely sure when the second question means, so... sorry, can't answer that one.

Brittany bought a dress that cost $22.50. If the sales tax is 6.5%, how much tax did she pay? PLZZ ITS TIMED
Start with your $22.50 subtotal (cost without tax)
Then, solve for 6.5% of $22.50
Set your equation up like so: 6.5/100=x/22.50
Cross multiply then you should have 100x=146.25
Solve to get 1.4625% (If you need it rounded, it's 1.5%)
1.5% ----> $1.46
$22.50+$1.56=$23.96
She spent $23.96
I'm pretty sure the answer's $1.46.
($1.46 is the amount of tax, not the total)
