Which of the following relations is a function?
• {(1.-6). (3. - 5), (1,0)
O None of the other answers are correct
Of(0,5), (5, -1). (5,9)
o {(6,1), (6,2), (6,3)}
o {(0,8), (1,7) (2,6)}
Answer:
I am awesome at these!!
Step-by-step explanation:
Only the last one is a function. This is because there are no repeating x values, which are the first numbers. It is okay for there to be repeating y values, but not x.

A deluxe bakery sells a cookie for $2.38, a brownie for $3.07 and a cake for $14.87. On Wednesday they sold 13 cookies, 4 brownies and 4 cakes. The cost in ingredients for each cookie is $1.7, for each brownie is $1.91 and for each cake is $5.83. How much profit did they make on Wednesday?
Answer:
$ 49.64
Step-by-step explanation:
Selling price of cookie on Wednesday = 13 × 2.38 = $30.94
Selling price for brownie on Wednesday = 4 × 3.07 = $ 12.28
Selling price for cakes on Wednesday = 4 × 14.87 = $ 59.48
Cost price for cookie = 13 × 1.7 = $ 22.1
Cost price for brownie = 4 × 1.91 = $ 7.64
Cost price for cakes = 4 × 5.83 =$ 23.32
Total profit for Wednesday= Total selling price - total cost price
That is;
(30.94 + 12.28 + 59.48) - (22.1 + 7.64 +23.32) = $ 49.64

9 hundreds equals how many tens
Answer:
90 tens
Step-by-step explanation:
900 = 10x
Variable x refers to how many 10's are needed to equal 900
To solve for this, divide both sides of the equation by 10
900 ÷ 10 = 10x ÷ 10
90 = 1x
90 = x
It will take 90 tens to equal 900

Joseph runs 2 miles on Monday. Each day after that, he runs the same 1 mile route every morning. His goal is to run at least 6 miles
by the end of the week. Which inequality represents the least number of days after Monday that Joseph needs to run to reach his goal?
Sine he runs 2 miles on Monday, we already have a +2.
Then, he runs by a constant rate of 1, which is the constant rate of change per day.
Let x represent the number of days he runs and y the total amount of miles he runs. Now, the equation is y = x + 2
However, he needs to run at least 6 miles. At least means greater than or equal to. The values for y can be greater than 6, or equal to 6.
y ≥ 6
y = x + 2
Now substitute x + 2 for y.
x + 2 ≥ 6
Subtract 2.
x ≥ 4
This is the inequality. He has to run for at least 4 days.

2/3x+3/4=8 what is the answer
Answer:
x=87/8
Step-by-step explanation:
2/3x=8-3/4
2/3x=32/4-3/4
2/3x=29/4
x=29/4*3/2
x=87/8
what is the coefficient of a^8b^2 in the expansion (1/3a^2 - 4b)^6
Step-by-step explanation:
(1/3a^2-4b)^6 for such an expansion the general term is
[tex]tr + 1 = \binom{6}{r} \times ( \frac{1}{3} {a}^{2} ) ^{6 - r} \times (4b)^{r} [/tex]
we want b^2 so r=2
so the formula transform to:
C6,2*(1/3)^4*a^8*4^2*b^2 so the coefficient of a^8b^2 is
(6*5/2*1)*(1/3^4)*4^2=
6*5*4*4/2*3*3*3*3=16*5/27=80/27

Helpp meee pleaseeeeeeeeeee !!!!
Step-by-step explanation:
since the domain of the function is given, you just have to plug in the numbers to the function:
13x - x²
it's basically asking: if x was any of the numbers in the given domain, what would it be the answer be?
for example:
I'll solve for -2 and you can do the rest.
13 • -2 -(-2 ²) =
13 • 2 + 4 =
26 + 4 = 30
so the range for -2 would be 30
If f (x) = one-ninth x minus 2, what is f>1(x)
Answer: f-1(x) = 9x + 18.
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x - 2 ( add 2 to both sides )
y + 2 = x
Multiply through by 9 to clear the fraction
9y + 18 = x
Change y back into terms of x
(x) = 9x + 18
Answer:
Answer: f-1(x) = 9x + 18.

HELP Lines a, b, c, and d intersect as shown below.
What is x
Answer:
x = 109°
Step-by-step explanation:
Angle x lies outside of line d, and is also positioned just on the side of line a that is opposite to the side of line a occupied by angle 109°.
Therefore, angle x and the angle measure of 109° are alternate exterior angles.
Alternate exterior angles are congruent.
x = 109°.

Choose the scenario below that matches this number sentence:
27 ÷ 5
A) 27 people share 5 bags of chips.
B) 5 people share 27 brownies.
Step-by-step explanation:
B 27 bags of chips by 5 people
Answer:
B) 5 people share 27 brownies.
Step-by-step explanation:
This is the answer because:
1) If 5 people are sharing 27 brownies, it means they are basically asking, how many brownies did each person get. Then, we would write the numerical sentence: 27 ÷ 5 because we want to know how many brownies each person got.
Hope this helps! :D

Create two tables with at least four coordinates each. In the first table, choose coordinates that make the relation a function. In the second table, choose coordinates that don't make the relation a function. Explain in complete sentences how you determined which coordinates would define a function and which coordinates would not.

Answer:
function: (1, 98), (2, 98), (3, 2), (4, -86)not a function: (1, 98), (2, 98), (3, 2), (3, -86)Step-by-step explanation:
A relation that is a function has unique x-values. A relation that is not a function has at least one x-value that is repeated. The y-values do not need to be unique in either case, except that a repeat of the same (x, y) pair does not disqualify a relation from being a function.
In the table shown above, the non-function has the x-value of 3 repeated with different y-values.
