Answer:
Los lados del triángulo rectángulo miden 3, 4 y 5, respectivamente.
Step-by-step explanation:
Un triángulo rectángulo puede ser descrito mediante el teorema de Pitágoras, para el caso de tres lados representando tres números enteros consecutivos, tenemos que:
(1)
Donde 
es un número natural.
A continuación, expandimos la expresión y resolvemos:
La única solución factible es 
. En consecuencia, los lados del triángulo rectángulo miden 3, 4 y 5, respectivamente.
Answer:
The answer is A. 
.
Step-by-step explanation:
To find the difference of this problem, start by simplifying the denominator, which will look like 
. Next, multiply 
by 
to create a fraction with a common denominator in order to subtract from 
. The problem will now look like 
.
Then, simplify the terms in the problem by first multiplying and , which will look like 
. The next step is to combine the numerators over the common denominator, which will look like 
.
Next, simplify the numerator, and to simplify the numerator start by factoring 3 out of 
, which will look like 
. Then, subtract 14 from -7, which will look like . The final answer will be .
Answer:
2
Offmind's Step-by-step explanation:
The Mode of a data set (<em>line plot in this case</em>) is the number which occurs most often. The line plot here shows the most x's on the number 2 than any other number so the mode is in fact, 2.
Bonus Fact: In another case, if there had been two numbers with the same amount of x's then those would both be considered the mode!

Answer:
1. Choice B
2. Choice C
3. X=-2
4. Choice A
5. y = 5/2 x + 5
Step-by-step explanation:
1.
the slope is down 3 over 2 m =-3/2
point slope form
y-y1= m (x-x1)
y-y1 = -3/2 (x-x1)
Choice B
2. (-3,-1) (1/2,2)
slope = (y2-y1)/(x2-x1)
m=(2--1)/(1/2--3) = (2+1)/(1/2+3) = 3/(3.5) = multiply top and bottom by 2
m = 6/7
point slope form
y-y1 = m(x-x1)
y--1 = 6/7 (x--3)
y+1 =6/7 (x+3)
multiply by 7
7y+7 = 6(x+3)
7y+7 = 6x+18
subtract 7y from each side
7 = 6x-7y+18
subtract 18 from each side
-11=6x-7y
Choice C
3. x=-2
This is a vertical line, the value of x never changes
4. (-1,2) (1,-4)
slope =(y2-y1)/(x2-x1)
= (-4-2)/(1--1) = -6/(1+1) = -6/2 = -3
point slope form
y-y1 = m(x-x1)
y-2 = -3(x--1)
y-2 = -3(x+1)
y-2 = -3x-3
add 2 to each side
y = -3x-1
Choice A
5. (-2,0) (0,5)
the y intercept is 5
slope is change in y over change in x
slope =(y2-y1)/(x2-x1) = (0-5)/(-2-0) = -5/-2 = 5/2
slope intercept form
y= mx+b
y = 5/2 x + 5
