Which set of ordered pairs represents y as a function of x?
Group of answer choices
{(0, 0), (1, 1), (1, 0), (2, 1)}
{(2, -1), (4, -2), (6, -3), (8, -4)}
{(1, -5), (1, 5), (2, -10), (2, -15)}
{(3, 3), (3, 4), (4, 3), (4, 4)}
{(2, -1), (4, -2), (6, -3), (8, -4)}
In this relation, each point has a unique x coordinate. None of the x coordinates repeat themselves.
For something like choice A, we have x = 1 repeated. The input x = 1 leads to multiple outputs (y = 1 and y = 0 simultaneously).
The same situation happens in choice C also. This time x = 1 and x = 2 repeat themselves.
Choice D has x = 3 and x = 4 repeat themselves.
A function is only possible if each x input leads to exactly one y output.

1.4x10^-7
Step-by-step explanation:
For Problem 6
First we would divide the first numbers together so 7.84 / 5.6 = 1.4
We then would add the exponenites together so -3+-4=-7
Leading our awnser to be 1.4x10^-7

Answer:
ik that angle one would be the same as 3 and 2 and 4 are also the same so if u find an answer for 2 or 4 they would be the same but is there like a total of the entire thing
Answer:
Angle 1 = 72 degrees
Angle 2 = 110 degrees
Angle 4 = 110 degrees
Step-by-step explanation:
Use angle rules.
Angle 2 + angle 3 = 180, because they supplementary angles. Therefore, to find angle 2, you can do 180 - 72 = 110 degrees.
Angle 1 and angle 3 are vertical angles, meaning they are equal. Thus, angle 1 = 72 degrees.
Angle 2 and 4 are vertical angles, meaning they are equal. Thus, angle 4 = 110 degrees.

Answer:
15 pieces of candy
Step-by-step explanation:
ok
45 / 3 = 15
15 x 2 = 30
she kept 30 pieces of candy
30 / 6 = 5
5 x 5 = 25
she had 25 pieces of candy after Monday
25 / 5 = 5
5 x 3 = 15
she had 15 pieces of candy after Tuesday
During a period of extreme cold, the average daily temperature dropped decreased by 1. Feach day. How many days did it take for the temperature to
decrease by 9 F? Which equation would you use to find the solution?
Answer:
The answer is 9 days
Step-by-step explanation:
First, we realise
-1.F = 1 day
-9.F = 9 days
The -1.F times 9 gives us one so the days times 9 as well.
Answer = 9

7 + ✓-25 what is the answer pls
Answer:
7 + 5i
Step-by-step explanation:
What is the square root of 25? Start by thinking about that.
Well, it's 5.
But because the 25 isn't positive, it's negative.
The square is 5i.
Then, you get 7 + 5i.
That can't be simplified any more, so that's your final equation.

Are lines m1 and m2 parallel? Explain Yes, because line m1 has a slope of -\frac{5}{2}− 2 5 and m2 has a slope of -2 No, because lines m1 and m2 have the same slope of -\frac{5}{2}− 2 5 No, because line m1 has a slope of -\frac{5}{2}− 2 5 and m2 has a slope of -2 Yes, because lines m1 and m2 have the same slope of -2 Item at position 2 2
Answer:
Yes, because lines m1 and m2 have the same slope of -2
Step-by-step explanation:
For given two lines L1 and L2 with slope m1 and m2 respectively, the condition for the two lines to be parallel is for the two equations to have the same slope. If m1 = m2, the meaning is that the line L1 and L2 are parallel to each other no matter the equation of the lines in question.
The general equation of a line is y = mx+c where;
m is the slope and c is the intercept.
Even though we are not given the equation of both lines, the base line is that for two lines to be parallel to each other, they must have the same slope.
The correct option is therefore "Yes, because lines m1 and m2 have the same slope of -2"

What is the slope of this equation?y= -1/2x −3 Question 2 options: 0 -3 -1/2
Answer:
-1/2
Step-by-step explanation:
In the equation y=mx+b..
y and x are the coordinates that go into your function
m is the slope
and b is the y intercept
looking at y=-1/2x-3 i can tell that -1/2 is in the place of m which is slope, and -3 is the y intercept.

Sam invests a sum of money in a retirement account with a fixed annual interest rate of 7%
compounded quarterly. After 13 years, the balance reaches $19,280.02. What was the amount of
the initial investment? ROUND YOUR ANSWER TO THE NEAREST DOLLAR (do NOT put a dollar
sign $ in your answer)
Answer:
The initial amount of investment was $7,822
Step-by-step explanation:
The formula for compound interest, including principal sum is:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex], where
A is the future value of the investment/loan, including interestP is the principal investment amount r is the annual interest rate (decimal)n is the number of times that interest is compounded per unit tt is the time the money is invested or borrowed forLet us use this rule to solve the question
∵ Sam invests a sum of money in a retirement account with a fixed
annual interest rate of 7% compounded quarterly
∴ r = 7% = [tex]\frac{7}{100}[/tex] = 0.07
∴ n = 4 ⇒ compounded quarterly
∵ After 13 years, the balance reaches $19,280.02
∴ A = 19,280.02
∴ t = 13
Substitute these values in the rule above to find P
∵ [tex]19,280.02=P(1+\frac{0.07}{4})^{4(13)}[/tex]
∴ [tex]19,280.02=P(1.0175)^{52}[/tex]
→ Divide both sides by [tex](1.0175)^{52}[/tex]
∴ 7,821.99888 = P
→ Round it to the nearest dollar
∴ 7,822 = P
∴ P = $7,822
∴ The initial amount of investment was $7,822.

The price of a sweater was reduced from $20 to $12 by what percentage was the price of the sweater reduced
If price of a sweater was reduced from $20 to $12 then the percentage was the price of the sweater reduced is 40%.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that the price of a sweater was reduced from $20 to $12.
Original price is 20.
new price is 12.
We have to find the how much percentage was the price of the sweater reduced.
To do this we have to find the difference between prices over the original price and multiply with 100.
Percentage = 20-12/20×100
=8/20×100
=40%
Hence, if price of a sweater was reduced from $20 to $12 then the percentage was the price of the sweater reduced is 40%.
