Answer:

The range of f is {1 , 3 , 4 , 7}

Step-by-step explanation:

* Lets revise the relation

- f is a relation between x and y

- x is the input of the relation

- y is the output of the relation

- x is called the domain of the relation

- y is called the range of the relation

- The range is the corresponding value to x

* Now lets solve the problem

∵ f = {(2 , 3) , (5 , 7) , (5 , 4) , (9 , 1)

∵ x = {2 , 5 , 9}

∴ The domain of f is {2 , 5 , 9}

∵ y = {1 , 3 , 4 , 7}

∴ The range of f is {1 , 3 , 4 , 7}

Answer: $Range:$ { $1,3,4,7$ }

Step-by-step explanation:

We know that, by definition, the Domain is the set of all the x-coordinates of the ordered pairs and the Range is the set of all the y-coordinates of the ordered pairs.

Therefore, given $f=(2,3),(5,7),(5,4),(9,1)$ , you can observe that the set of all second elements of ordered pairs (the values of "y") is the following:

{ $3,7,4,1$ }

Therefore, we can conclude that if $f=(2,3),(5,7),(5,4),(9,1)$ , then the range is:

$Range:$ { $1,3,4,7$ }

bulgar [2K]

Question is not proper, Proper question is given below;

36% of the beans in Pythagoras's soup are lentils, and 33 1/3% of those lentils are green.

If Pythagoras removes all green lentils from his soup, then x% of the original beans remain. What is x?

Answer:

88% of the original beans remains $(x)$ after removing green lentils.

Step-by-step explanation:

Given:

Let the Original beans be 'n'.

Now given:

36% of the beans in Pythagoras's soup are lentils.

So we can say that;

Amount of lentils = $\frac{36}{100}n=0.36n$

Also Given:

33 1/3% of those lentils are green

Amount of green lentils = $33\frac{1}{3}\%\ \ Or \ \ \frac{100}{3}\%$

Amount of green lentils = $\frac{100}{3}\times 0.36n\times\frac{1}{100}= 0.12n$

Now we need find the percentage of original beans remain after removing green lentils.

Solution:

percentage of original beans remain ⇒ $x\%$

To percentage of original beans remain after removing green lentils we will subtract Amount of green lentils from Original beans and then multiplied by 100.

framing in equation form we get;

$x\%$ = $(n-0.12n)\times 100=88n \ \ \ Or \ \ \ 88\%$

Hence 88% of the original beans remains $(x)$ after removing green lentils.

Answer: $\Large\boxed{A.~y=3x+4}$

Step-by-step explanation:

Given information

Slope = 3

Point = (-3, -5)

Given the format of the equation

Slope-intercept form: y = mx + b

m = Slope
b = y-intercept

Substitute values into the equation

y = (3)x + b

y = 3x + b

Substitute the given point into the equation to get the value of [ b ]

(-5) = 3(-3) + b

-5 = -9 + b

b = -5 + 9

b = 4

Therefore, the equation of the line is $\Large\boxed{y=3x+4}$

Hope this helps!! :)
