Answer: 3) (-1,-4)

Step-by-step explanation:

We define a function as a relationship that maps elements from one set (inputs) into elements of another set (outputs).

The functions have one important rule, each element in the domain (the set of possible inputs) can be mapped into only one element in the range (set of possible outputs).

Then if we have:

a ≠ b

and for an input x0.

f(x0) = a

and

f(x0) = b

this is not a function, as it maps the value x0 into two different values.

Then we know that the points  {(-2,3),(-1,4),(0,5)} define our function.

Then the option that makes this relation to not be a function, will be any point that has the same input as some of the above ones, and different output.

the correct one is 3) (-1, -4)

Then the set will be:

{(-2,3),(-1,4),(0,5), (-1, -4)}.

Now we have two times the input -1, and different outputs, then this is not a function.

(-1, -4) would create a set that no longer represents a function.

Note that a relation is a function if each value of x is matched to only one value of x.

A relation does not qualify to be a function if one value of x is matched to more than one value of y.

For a function defined by the set of ordered pairs {(-2,3),(-1,4),(0,5)}:

The addition of an x-value that is already in the function will make the x-value to be matched to more than one y-value. This will disqualify the relation from being a function.

By considering the options given:

The option (-1, -4) would create a set that no longer represent a function because at x = -1, the values of y will be 4 and -4, which will make the graph fail the vertical line test

Answer:

Bruh

Step-by-step explanation:

Im so confused.... lol im not any help

What you're looking for is to simplyfy the like terms and then isolate the variable. So basically, write everything down and solve it like normal. We know that straight lines are worth 180° and right angles are 90° so that's what's gonna be on one side of the equal sign, and all the other numbers on the other side. Like this:

8.

180 = x + 1 + 3x + 9

180 = 4x + 10

170 = 4x

42.5 = x

If it's hard to see what I'm doing, just write the first part out and solve like regular algebra then check if you got the same answer.

Good luck :)

Answer: The answr is y=5/36 If my math is correct

Since the question is y=25/9 and x was 5 and z was 1, I thought 5 x 5 is 25, so x is 5. and 1 x 9 is 9 so z is 9. so then i multiplied 9x4 for z and 5 x 1 for x

Question:

The probability that a UCR undergraduate majors in Nursing is 0.15. The  probability that a UCR undergraduate is a Junior is 0.20. The probability that a UCR  undergraduate is a Junior or a Nursing major is 0.085. What is the probability that a UCR  undergraduate is a Junior and a Nursing major?

Answer:

[tex]P(J\ and\ N) = 0.265[/tex]

Step-by-step explanation:

Given

Represent Junior with J and Nursing Major with N.

So, we have:

[tex]P(N) = 0.15[/tex]

[tex]P(J) = 0.20[/tex]

[tex]P(J\ or\ N) = 0.085[/tex]

Required

Determine [tex]P(J\ and\ N)[/tex]

In probability, for events A and B

[tex]P(A\ and\ B) = P(A) + P(B) - P(A\ or\ B)[/tex]

In this case:

[tex]P(J\ and\ N) = P(J) + P(N) - P(J\ or\ N)[/tex]

Substitute values for P(J), P(N) and P(J or N)

[tex]P(J\ and\ N) = 0.20 + 0.15 - 0.085[/tex]

[tex]P(J\ and\ N) = 0.265[/tex]

Hence, the probability that an undergraduate is a Junior and major in Nursing is 0.265

Answer:

0.50

Step-by-step explanation:

To answer this question, we have the following data available:

Probability of randomly chosen death caused by a heart disease = 0.27

Probability of randomly chosen death caused by cancer = 0.23

We are to calculate the probability that the death was as a result of either cancer or heart disease.

P(cancer or heart disease)

= 0.27 + 0.23

= 0.50

Answer:

437.90

Step-by-step explanation:

you add the negative numbers together, then the positive numbers. you take the answers from those and subtract them from each other.

The overall loss for the first four months the deli was open is $-437.90.

A firm has a profit when its income is greater than the cost. A loss is recorded when income is less than the total costs. A profit is represented with a positive sign (+) and a loss is represented with a negative sign (-).

In order to determine the overall profit or loss for the first four months add profits and subtract losses.

+ 724.37 + 3,912.26  - 1,051.51 - 4,023.02 = $-437.90.

Costs exceeds revenue so the Deli earns a loss of $437.90.

Answer is 7/3

The function that represents the relationship between x and y is (y = 4x) and this can be determined by using the given data.

Given :

The following steps can be used in order to determine the function that represents the relationship between x and y:

Step 1 - According to the given data, the value of 'y' varies directly with 'x'. So, the mathematical expression for this situation is:

[tex]y \; \alpha \; x[/tex]

y = kx    --- (1)

Step 2 - It is also given that the value of y = 14 when x = 7/2.

Step 3 - Now, substitute the value of 'y' and 'x' in the above expression.

[tex]\rm 14=\dfrac{7}{2}\times K\\[/tex]

K = 4

Step 4 - Now, substitute the value of K in the expression (1).

y = 4x

Step-by-step explanation:

slope is -1/2 beware this is a negitive slope so it goes down like this \

go one up and go to the left 2 times and connect the dots

Starting with some solution of volume v and an alcohol concentration of 100c % , if you add 180 mL of 45% isopropyl to it, you get a mixture with a total volume of 180 mL + v.

Each mL of the starting solution contains c mL of alcohol. For example, if the concentration of the starting solution is 80% (so c = 0.8), then each mL contains 80% = 0.8 of one mL of alcohol.

Similarly, each mL of the added solution with 45% concentration contains 0.45 mL of alcohol.

You want the new solution to have a concentration of 70%, so that the ratio of the amount of alcohol in it to the total volume is 70%, meaning

cv + 0.45 (180 mL) = 0.7 (180 mL + v)

and you want to solve for v :

cv + 81 mL = 126 mL + 0.7v

cv - 0.7v = 126 mL - 81 mL

(c - 0.7) v = 45 mL

v = (45 mL) / (c - 0.7)

Judging by context clues, c lies somewhere between 0.7 and 1. (It can't be less than 0.7 because mixing this solution with any other solution of smaller concentration will never yield a solution of higher concentration.)

If, for example, c = 0.8, so that your starting solution is at 80% concentration, then you would need

v = (45 mL) / (0.8 - 0.7) = 450 mL

to be mixed with 180 mL of 45% solution to end up with 180 mL + 450 mL = 630 mL of 70% solution.

As another example, if you're mixing pure alcohol, so that c = 1, you would need

v = (45 mL) / (1 - 0.7) = 150 mL

to make a 180 mL + 150 mL = 330 mL batch of 70% solution. The fact that you would need less of a higher concentration solution is not surprising.
