a) Dos números enteros positivos se diferencian en 6 unidades y la suma de sus cuadrados
es 260. ¿Cuáles son esos números?
Queremos encontrar dos números enteros tales que su diferencia sea de 6 y la suma de sus cuadrados sea igual a 260.
Veremos que los dos números son 8 y 14.
Primero, podemos definir esos números como A y B.
Entonces tenemos que:
A - B = 6
A^2 + B^2 = 260
Esto es un sistema de ecuaciones.
Para resolverlo, el primer paso es aislar una de las variables en una de las ecuaciones, vamos a hacer esto en la primera.
A - B = 6
A = 6 + B
Ahora reemplazamos esto en la otra ecuación.
A^2 + B^2 = 260
(6 + B)^2 + B^2 = 260
36 + 12*B + B^2 + B^2 = 260
36 + 12*B + 2*B^2 = 260
Ahora podemos resolver esto para B:
2*B^2 + 12*B + 36 - 260 = 0
2*B^2 + 12*B - 224
Las soluciones estan dadas por la formula de Bhaskara:
[tex]B = \frac{-12\pm \sqrt{12^2 - 4*2*(-224)} }{2*2} \\\\B = \frac{-12 \pm 44 }{4}\\\\B = (-3 \pm 11)[/tex]
Entonces las dos soluciones son:
B = -3 + 11 = 8
B = -3 - 11 = -14
Sabemos que los números son positivos, asi que elejimos la primera, entonces tenemos:
B = 8.
Con esto podemos calcular el valor de A como:
A - B = 6
A = 6 + B = 6 + 8 = 14
Entonces los dos números son:
8 y 14.

a line passes through the point (10,-5) and a slope of -3/2
Write an equation in slope-intercept form for this line.
Answer:
y = -3/2x + 10
Step-by-step explanation:
The slope = -3/2
Using the slope = -3/2 and the point (10, -5) substitute into y = mx + b and solve for "b"
y = mx + b
-5 = -3/2(10) + b -3/2 · 10 = -30/2 = -15
-5 = -15 + b
-5 + 15 = b
10 = b
The equation of the line is y = -3/2x + 10

How do you solve this and find x?
Answer:
fraction form
x= 2 + ln(30)/ln(7)
decimal form
x= 3.74786969
Step-by-step explanation:
What I like to call the logarithmic equation solver.
Bring it down turn it around.
First bring down the 7 to a ㏒7 and the x-2 so that ㏒7(x-2)=30
Then change the constants from on another so then it would look like
㏒7(30)=x-2
solve for x
to solve do the log base finder equation ㏒(30)/ln(7)
and add 2

help me please! find the angles and solve for x!!!
Answer:
x = 25; 47 degrees, 47 degrees, 86 degrees
Step-by-step explanation:
the two triangles are congruent so they have the same angles
that means 2x - 3 = x + 22
2x - 3 = x + 22
subtract x from each side
x - 3 = 22
add 3 to both sides
x = 25
and this is your answer
assuming that the triangles are isosceles triangles two of the angles are the same
the angles with the x on it are 47 after calculating
that means that the other angle across from it is also 47
a triangles angles added up is 180
47 + 47 + n = 180
the last angle after calculating is 86 degrees

Tyana swims at a constant speed, 4 meters every 5 seconds. How long does it take her to swim 20
meters? Solve using two different methods
Answer:
25 seconds
Step-by-step explanation:
Two methods:
1) Calculate Tyana's speed in m/sec: 4m/5sec = 0.8 m/sec. Now find the number of seconds, x, needed to travel 20 meters:
x*(0.8 m/sec) = 20 m
x = 20 m/(0.8 m/sec)
x = 25 seconds
2) Do a proportion. If Tyana can swim 4 meters in 5 sec, then she can do 8 meters in 10 seconds. That also then means 16 meters in 20 seconds. Another 5 seconds adds another 4 meters, for a total of 20 meters in 25 seconds.

Use point-slope form to write the equation of a line that passes through the point
(-3, -16) with slope – 2/1
Answer:
y= -2x-22.
Step-by-step explanation:
1) the slope-interception common form is y=s*x+i, where 's' and 'i' are the slope and interception, unknown numbers;
2) if x₁= -3; y₁= -16, and s=-2, then the equation of the required line can be written in the point-interception form y-y₁=s(x-x₁); ⇔ y+16= -2(x+3);
3) the required equation in slope-interception form is:
y+16= -2x-6; ⇒ y= -2x-22.
note, the provided solution is not the only and shortest way.
