Answers
Answer:
y = 2x
PRIMARY METHOD
Identify two points, find their slope, and write an equation
(1, 2) and (3, 6)
m = (y₂ - y₁)/(x₂ - x₁)
m = (6 - 2)/(3 - 1) = 4/2
m = 2
(1, 2)
y - y₁ = m (x - x₁)
y - 2 = 2 (x - 1)
y = 2x - 2 + 2
y = 2x
SIMPLER METHOD
Rise/Run
(0,0) to (1, 2) = 2/1 = 2
(1, 2) to (3, 6) = 4/2 = 2
Answer:
y = 2x
Step-by-step explanation:
The graph shows a straight line that passes trhough the origin, so it is a direct proportion relation with equation of the form y = mx.
To find the slope, use any easy-to-read point, and divide the y-coordinate by the x-coordinate. For example, use (1, 2).
m = 2/1 = 2
y = 2x

i just did wrong so the person below me is correct
Step-by-step explanation:
Answer:
A: 15
Step-by-step explanation:
It is asking for the hypotenuse of the triangle. To find this, use pythaogreans theorem.
A^2 + B^2 = C^2
In this case,
9*9 + 12*12 = C*C
81 + 144 = C*C
225 = C*C
Now do the square root of both sides and you get
15 = C. Therefore the missing length is 15.

A coin is Flipped 3 times. What IS the probability that the coin lands heads up once and tails up twice if order does not matter?
Answers
Answer:
The probability that the coin lands heads up once and tails up twice is .375, or 3/8.
Step-by-step explanation:
Check the conditions for a binomial distribution problem:
Define success = heads and failure = tails.The number of trials is fixed; n = 3.Each coin flip is independent of the other.Probability p = .5 of getting either heads or tails.We need to use combinations to determine the probability of getting one success (one head) and two failures (two tails).
The combination would be 3 choose 1: [tex]p = {3 \choose 1} (.5)^1(.5)^2[/tex].
There is one success and two failures, denoted by the superscripts above the probability p = .5.
Use a calculator to evaluate and we get:
[tex](3)(.25)(.5) = .375[/tex]The probability that the coin lands heads up once and tails up twice is .375, or 3/8.

Applying the distance formula, the distance from from Tia's home to Lei's home = 14.4 units.
What is the Distance Formula?The distance formula helps us to find the distance between two given coordinate points. It is expressed as, [tex]\mathbf{d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} }[/tex].
Tia = (4, 8) = (x1, y1)
Lei = (12, 20) = (x2, y2)
Apply the distance formula to find the distance from Tia's home to Lei's home:
d = √[(12−4)² + (20−8)²]
d = √[(8)² + (12)²]
d = √(64 + 144)
d = √208
d ≈ 14.4 units
The distance from from Tia's home to Lei's home = 14.4 units.

Use the associative property
write an equivalent expression.
(5 + 7) + x =
Answers
5+(7+x)
Step-by-step explanation:Finding an Equivalent Expression
The associative property of addition states that you can move the terms that are inside the parentheses and still have the expression remain true. So, in the answer above, I moved 5 out of the parentheses and x into the parentheses. No matter the value of x the value of the expression will remain the same
Examples and Proof
Another example of the associative property could be (1+6)+3 = 1+(6+3). To prove this statement we can evaluate each side of the expression.
First, let's do (1+6)+3
(1+6)+3(7)+310Next, let's do 1+(6+3)
1+(6+3)1+(9)10As you can see both of these expressions are the same, thus proving that the associative property works in this situation.

(This is from Aleks)
Answers
Answer:
Q: 875 R: 4
Step-by-step explanation:
If you dont like doing long division, try plugging values in usling a calculator! Estimate tht 5*8=40, and then, 5*800 must then equal 4000, which is pretty close to 4374
5*7=35, so the 5*70 must equal 350
5*4 equals 20, so when you add these values up you get...
4000+350+20...
or 4370
and, since 4374-4370 equals 4, your remainder would be 4!
