equation form: y = mx + b
where m is the slope, and b is the y-intercept.
slope = (y2 - y1) / (x2 - x1) = (13 -8) / (11 - 5) = 5/6
y = 5/8 x + b (replace x and y by 5 and 8)
=> 8 = 5/6 * 5 + b
=> 8 = 25/6 + b
=> b = 8 - 25/6 = 23/6
==> equation: y = 5/6 * x + 23/6

Answers
Answer:
0.01085 ~ 1.085%
Step-by-step explanation:
Okay so a simple way to do these probability ones is to add an extra space around each side
YES NO
POSITIVE 325 2 _____
NEGATIVE 16 1131 _____
_____ _____ _____
Now in these spaces add all the the rows and columns accordingly
YES NO
POSITIVE 325 2 _327_
NEGATIVE 16 1131 _1147_
_341_ _1133_ _1474_
Now the number in the place where the additional rows meet is your total number of patients, so this is what you would use for your probability.
So we are looking for YES / NEGATIVE which is 16
Now do 16 divided by 1474 and your probability comes out to 0.01085..., so as a percentage, would be 1.085%
Hope that helped :)

Answer:
x= 1 and y =1
Step-by-step explanation:
4+4 is 8, therefore for this to be true both must be 1
Answer:
x = 1; y = 1
Step-by-step explanation:
We know x and y have to equal the same thing because 4 + 4 = 8
x = 4 / 4
y = 4 / 4
x = 1
y = 1
Therefore, x = 1; y = 1
Question 3 "Try Again." Mary needs 3 feet of boondoggle for a craft project.
Boondoggle costs $0.25 per inch. How much will the project cost Mary?
Answers
Answer:
$9.00
Step-by-step explanation:
We can use conversion factors to solve this equation. The multiplication sequence that I got is shown below:
[tex]\frac{3ft}{1}[/tex] × [tex]\frac{12 in}{1ft}[/tex] × [tex]\frac{0.25}{1in}[/tex]
Our feet and inches cancel out and we get the final expression [tex]\frac{3*12*0.25}{1}[/tex], which is equal to 9, or $9.00.
Hopefully that was helpful! :)

What is the equation of a line that is perpendicular to the line y=2x+1 and passes through the point (4,6)?
Answers
Answer:
y = - [tex]\frac{1}{2}[/tex] x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 1 ← is in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex] , then
y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (4, 6 ) into the partial equation
6 = - 2 + c ⇒ c = 6 + 2 = 8
y = - [tex]\frac{1}{2}[/tex] x + 8 ← equation of line

Perpendicular lines have the product of their gradient equal to -1
For L1,the gradient is 3

The slope is -⅓
Now product of both slopes 3×-⅓=-1,thus the lines are perpendicular

What is the ratio of the number of beaks to the number of legs the chickens and the sheep have on this farm?
Answers
Answer: 1:9
Step-by-step explanation:
If you multiply 2 legs times 8 chickens we get 16
If you multiply 4 legs times 14 sheep we get 56
The number of legs is 16+56=72
So you have 8 beaks and 72 legs or 8:72
Divide both sides by 8 to simplify and you get 1:9 as the answer
(81)¾ - (27)⅓
\3 × 2³
Answers
Answer:
I won't tell you the answer but if you read the solution, you would understand it.
Step-by-step explanation:
81^3/4 is basically 3 times the fourth root of 81. What number multiplies 4 times to make 81? Then multiply that by 3.
Now we have the cube root of 27. If you have a fractional exponent with no numerator, that just means square root, cube root, fourth root.
Eg. the exponent 1/4 would just mean fourth root
Eg. The exponent 1/2 would just mean square root
The cube root of 27 is 3.
The denominator is 3 times 2 to the third power.
PEMDAS
Order of Operations tells us we do exponents first so 2 to the third power is 8 and multiply by that 3.

Second Question:
5x + 2x = 7x
5x^2 + 3x^2 = 8x^2
2x + 3x - x = 4x
2x + 3y + x + y = 3x + 4y
9x - 6x = 3x
-7y + 3x + 4x + 3y = 7x - 4y
-7x^2 + 2x^2 + 9x^2 = 8x^2
(3x^2 + 5x + 4) - (-1 + x^2) = 2x^2 + 5x + 5
(3 + 2x - x^2) + (x^2 + 8x + 5) = 10x + 8
(3x - 4) - (5x + 2) = -2x - 6
(2x^2 + 5x + 3) - (x^2 - 2x + 3) = x^2 + 7x
(3x^2 + 2x - 5) - (2x^2 - x - 4) = x^2 + 3x - 1
Third Question:
17x + 2y
