Answer:
the slope is 12
Step-by-step explanation:
y=12x+1 is from the formula y=mx+b where m is the slope and b is the y-intercept.
Since 12 has replaced m, it is the slope.
Since 1 has replaced b, it is the y-intercept.
"the slope is 12" is the correct answer choice.

Datos solu
Answer:
a. A Estela le entregaron (100 + 30 + 3) tejuelones = 133 tejuelones y aún necesita (138 - 133) tejuelones = 5 tejuelones para que reciba todo el pedido. b. Don Antonio llevó (150 + 60 + 7) tejuelones = 217 tejuelones.
Step-by-step explanation:
Parte a¿Cuántos tejuelones le entregaron a Estela? ¿Cuántos tejuelones es la diferencia para que Estela reciba todo el pedido realizado?
Datos
Pedido de Estela:
138 tejuelones.
Le entregaron:
Dos (2) Paquetes de 50 tejuelones.
Dos (2) Paquetes de 15 tejuelones.
Tres (3) Sueltos.
Operación
Para determinar cuántos tejuelones le entregaron a Estela, efectuamos las siguientes operaciones para determinar el número de tejuelones que le entregaron:
Dos (2) Paquetes de 50 tejuelones
2 * 50 tejuelones = 100 tejuelones
Dos (2) Paquetes de 15 tejuelones
2 * 15 tejuelones = 30 tejuelones
Es decir, multiplicamos el número de paquetes por la cantidad de tejuelones que trae cada uno.
Ahora sumamos el total de ambas cantidades y le adicionamos los tres (3) tejuelones sueltos:
(100 + 30 + 3) tejuelones = 133 tejuelones.
Pero Estela pidió 138 tejuelones, así que aún necesita:
(138 - 133) tejuelones = 5 tejuelones para que reciba todo el pedido realizado.
Respuestas
¿Cuántos tejuelones le entregaron a Estela?
A Estela le entregaron (100 + 30 + 3) tejuelones = 133 tejuelones.
¿Cuántos tejuelones es la diferencia para que Estela reciba todo el pedido realizado?
Estela aún necesita (138 - 133) tejuelones = 5 tejuelones para que reciba todo el pedido.

Operaciones
Para determinar cuántos tejuelones le entregaron a Don Antonio, debemos multiplicar el número de paquetes por la cantidad de cada uno y sumar los siete (7) tejuelones sueltos, es decir, seguimos el mismo procedimiento de la pregunta anterior.
Tres (3) paquetes de 50 tejuelones
3 * 50 tejuelones = 150 tejuelones.
Cuatro (4) paquetes de 15 tejuelones
4 * 15 tejuelones = 60 tejuelones.
Ahora sumamos estas cantidades y le adicionamos los siete (7) tejuelones sueltos:
(150 + 60 + 7) tejuelones = 217 tejuelones.
Respuesta
¿Cuántos tejuelones llevó Don Antonio?
Entonces, considerando los resultados anteriores, tenemos que Don Antonio llevó (150 + 60 + 7) tejuelones = 217 tejuelones.

Just 20 and 21...also there’s a little hint it says to draw a triangle.
Answer:
20. 13 cm
21. 12 cm
Step-by-step explanation:
20. isosceles means two sides are the same length, so you take the ten off the perimeter to get 26 remaining cm (36 -10) and you then divide that by two to get both sides of 13 cm (26 / 2)
21. because you know that if you split the triangle down the middle you get a right triangle and you can use a^2+b^2=c^2 to find the height, so we take the one side of 13 cm and half of the third side, which is 5, and you can find your answer (a^2 + 5^2 = 13^2 ---> a^2 + 25 = 169 ---> a^2 = 144 ---> a = 12)

When you flip a biased coin the probability of getting a tail is 0.75.
How many times would you expect to get tails if you flip the coin 160 times?
Answer:
You would expect to get tails 120 times
Step-by-step explanation:
0.75 * 160 = 120
Answer:
120
Step-by-step explanation:
to find the number of times, you expect to get tails:
multiply 160 by 0.75.
you could also multiply 160 by 3/4, which is easier, but still gives the same answer.
3/4 x 160 = 3 x 40 = 120

8. Write the equation of the line in slope-intercept form that passes through (10.21) and (15.36)
Answer:
y = 3x - 9
Step-by-step explanation:
First, find the slope using y2 - y1 / x2 - x1
36 - 21 = 15
15 - 10 = 5
15/5 = 3, so the slope (m) is 3.
Now, plug into point-slope form: y - y1 = m (x - x1)
y - 21 = 3 (x - 10)
Simplify
y - 21 = 3x - 30
y = 3x - 9

Ummm help someone who knows what they doing
Answer:
X = - 6
Step-by-step explanation:
18x + 30 = 6(2x – 1)
Multiply 6 to 2x and - 1
18x + 30 = 12x – 6
Subtract 30 on both sides
18x = 12x – 36
Subtract 12x on both sides
6x = - 36
Divide by 6 on both sides
X = - 6

Answer:
10/9
Step-by-step explanation:
average rate of change in 0≤x≤9
=(3-(-7))/(9-0)=10/9
Answer:
The solution is 10/9
Step-by-step explanation:
Step 1: identify the right approach:
Given a function g(x) over a period of time, to find the average rate of change of g(x) over this period of time, we divide the change in g(x) by the change in x.
Step 2: Perform the calculation:
As shown in picture,
x = 0 => g(x) = -7
x = 9 => g(x) = 3
=> The change of x over interval [0, 9] is:
x_change = 9 - 0 = 9
=> The change of g(x) over interval [0, 9] is:
g(x)_change = 3 - (-7) = 10
=> The average rate (r) of change of g(x) over interval [0, 9] is:
r = g(x)_change/x_change = 10/9
