Is the relation a function? Why or why not?

{(3, –1), (3, 0), (–3, 4), (3, 8)}

Yes; only one range value exists for each domain value.
No; three range values exist for domain value 3.
No; the relation passes the vertical-line test.
Yes; three range values exist for domain value 3.

Answers

Answer 1

Answer:

B

Step-by-step explanation:

An x can't have 2 y values and it still be a function. If it fails the vertical line test, it is not a function.

Answer 2

Answer:

I believe the answer is B: No; three range values exist for domain value 3.

Step-by-step explanation:

I believe this is the answer because I know the relation is not a function, so it isn't A. or D.  Then I graphed the points and confirmed the answer is not C. because the relation does not pass the vertical -line test.  

So I believe the answer is B. because, if the points are graphed, three of the points are in a vertical line with the value of 3, while one is in a domain value of -3.

Step-by-step explanation:

help pls im trying to figure out my money i'm saving for a phone ill give brainliest if u can help. i have $16 rn and on march 12th is the 1st day of allowance which is $5 after the end of that week. ill get $5 every week. how long will it take for me to get $303?

Answers

ANSWER : About 15 months. Because 5 x 4 = 20 (4 weeks in a month)

303 Divided by 20 is 15.15. (it's ok I dont need brainliest!)

Answer:

61 (from first pay-week) or about a year and two months

Step-by-step explanation:

then all we have to do is divide that by the amount of money you ern per week (in the case 5) and that will be the amount of allowance days that will take u to your goal

303 / 5 = 60.6

if you want to simplify it, we can round up to 61 weeks wich is about a year and 2 months IF your allowance rate stays the same

however dont feel bad, as time goes on many factors may change this, maybe your allowance may be a little larger, and trust me, a few cents can shave of months sometimes, another thing is that the phone may lose value over time and you may be able to get it before you reach your goal

and keep on the lookout, where theres an expensive item, there is sometimes a WAY cheaper alternative where you may sacrifice a little bit somewhere, but will be worth it in the end

look in the positive direction, it may seem impossible at first, but trust me, this is an achievable goal, good luck mate :D

The slope of the line for the graph representing the taxi cost is steeper than the slope of the line of the graph representing the town car.
The slope of the line for the graph representing the town car cost is steeper than the slope of the line of the graph representing the taxi.
The y-intercept on the graph of the town car is greater than the y-intercept of the graph of the taxi.
The y-intercept is zero for both graphs.

the third one because the initial fee is $2.50 for the taxi so thats where the line is going to start there. the initial fee for the car is $3 so it will start there. $3 is more than $2.50 so its the third one.

Select the two expressions that are equivalent to 4 + w + 12w.

a
4 + 13w
b
13w2 + 4
c
2(2 + 6w) + w
d
16 + 2w
e
2(2 + 6w2)

Answers

The answer are
A and B

The equivalent values of the expression A = 4 + w + 12w are B = 4 + 13w and C = 2 ( 2 + 6w ) + w

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

To find the expressions that are equivalent to 4 + w + 12w, we need to simplify the expression and see which of the given expressions have the same result.

4 + w + 12w = 4 + 13w

So, the equivalent expressions are (a) 4 + 13w and (c) 2(2 + 6w) + w.

Let's check the other options:

(b) 13w² + 4: This is not equivalent, as it involves squaring the w term.

(d) 16 + 2w: This is not equivalent, as it involves adding a constant term.

(e) 2(2 + 6w²): This is not equivalent, as it involves squaring the 6w term.

Hence , the two expressions that are equivalent to 4 + w + 12w are (a) 4 + 13w and (c) 2(2 + 6w) + w.

Step-by-step explanation:

The formula is, b(base)+c(height)= b+c over 2.  b+c/2.

B=19ft in this problem.

C=38ft

Knowing this, we can further simplify.

19+38/2

Which relation is a function?

{(5, 0), (–8, –5), (–8, 5), (–5, –8)}
{(5, 0,) (–8, –5)}
{(5, 0), (0, 5), (–5, –5)}
{(5, 0), (0, –8), (5, –5)}

Answers

Answer:

B. C.

Step-by-step explanation:

when you have a function, you can only have one input for every output, like in A

{(5, 0), (-8, -5), (-8, 5), (-5, -8)}

we have -8 twice in the sets of numbers on the X, so this set is NOT a function

another way to tell is to plot out the points on the graph, then draw a vertical line and run across the sets, if more then one point cross the line at a time, then those points are not a function, this is called a vertical line test

hope this helps, it looks like a multiple choice maybe, bc B. and C. are both functions from what i can see, i hope this was worth the points u spent on this question
