The slope of the graphed linear equation is a = 3/4.
What is the slope of the graphed linear function?A general linear equation is of the form:
y = a*x + b
Where a and b are real numbers, a is the slope, and b is the y-intercept.
If a line passes through two points (x₁, y₁) and (x₂, y₂), then the slope of that linear equation is given by:
a = (y₂ - y₁)/(x₂ - x₁)
Now, we can look at the graph to identify two points on the line, we can use (20, 40) and (60, 70), using the above formula we can get the slope:
a = (70 - 40)/(60 - 20)
a = 30/40 = 3/4
The slope of the graphed linear equation is a = 3/4.

Find the first four terms of the sequence given by the following.
a₁ = -3.5"-1 n=1, 2, 3
the first four terms of the sequence is 51,51.8,52.6,53.4
we can find first four terms by using formula given by
[tex]a_{n} =a_{1} +(n-1) *d[/tex]
[tex]a_{n}[/tex] = the nᵗʰ term in the sequence
[tex]a_{1[/tex] = the first term in the sequence
d = the common difference between terms
Arithmetic progression is a progression in which every term after the first is obtained by adding a constant value, called the common difference (d). So, to find the nth term of an arithmetic progression, we know an = a1 + (n – 1)d. a1 is the first term, a1 + d is the second term, the third term is a1 + 2d, and so on
an=51 + (n-1)*0.8, n=1, 2, 3...
a1 = 51 + (1 -1 ) * 0.8
a1 = 51
a2 = 51 + (2 - 1)*0.8
a2 = 51 + 0.8
a2 = 51.8
a3 = 51 + (3 - 1)*0.8
a3 = 51 + 2*0.8
a3 = 51 + 1.6
a3 = 52.6
a4 = 51 + (4 - 1)*0.8
a4 = 51 + 2.4
a4 = 53.4
Hence , the first four terms of the sequence is 51,51.8,52.6,53.4
the complete question is

A parallelogram is drawn such that the diagonals are congruent. Which shape below would not fit this description?
The shape that would not fit this description is a trapezoid.
What is a trapezium?It is a quadrilateral that has one pair of parallel sides and a height.
The area is calculated as 1/2 x the sum of the parallel sides x height.
Examples:
Area of a trapezium that has the parallel sides as 3 cm and 4 cm and a heght o 5 cm.
Area = 1/2 x (3 + 4) x 5
Area = 1/2 x 7 x 5
Area = 35/2 = 17.5 cm^2
We have,
A parallelogram is a four-sided shape where opposite sides are parallel and congruent.
If a parallelogram has diagonals that are congruent, it must be a rectangle.
Therefore, the shape that would not fit this description is any shape that is not a rectangle.
Out of the shapes given,
A trapezoid is not a rectangle and does not have diagonals that are congruent.
Therefore,
The shape is a trapezoid.

An architect built a scale model of a sports stadium using a scale in which 2 inches represents 30 feet. The height of the sports stadium is 180 feet. What is the height of the scale model in inches?
Answer:
12 inchesStep-by-step explanation:
Given the conversion factor;
2inches = 30feet
if the height of the building is 180feet, we are to find the height of the scale model in inches.
Let x = 180 feet.
Equating both;
2inches = 30feet
x inches = 180feet
Cross multiply;
30 * x = 2 * 180
30x = 360
x = 360/30
x = 12inches
Hence the height of the scale model in inches is 12inches
Answer: 60 in
Step-by-step explanation:Let x = 180 feet.
Equating both;
2 inches = 30 feet
x inches = 180 feet
Cross multiply;
30 * x = 2 * 180
30 x = 360
x = 360/30
x = 60 inches
A line contains the points (82, −96) and (87, −86).
What is the slope of the line in simplified form?
Answer:
The slope is 2.
Step-by-step explanation:
ΔX = X2 - X1 = 87 - 82 = 5
ΔY = Y2 - Y1 = -86 - (-96) = -86 + 96 = 10
ΔY/ΔX = 10/5 = 2/1 = 2

1. Un representante de ventas debe visitar 6 ciudades durante un viaje. a) Si hay 10 ciudades en el área geográfica que va a visitar ¿Cuántos grupos diferentes de seis ciudades podrá seleccionar? b) Suponga que las seis ciudades por visitar han sido designadas, pero no la secuencia en que se han de visitar ¿Cuántas secuencias posibles existen para las seis ciudades designadas?
Answer:
a) Hay 210 grupos diferentes de seis ciudades que el representante de ventas podrá seleccionar.
b) Hay 720 secuencias posibles existen para las seis ciudades designadas.
Step-by-step explanation:
a) Se llama combinaciones de m elementos tomados de n en n a todas las agrupaciones posibles que pueden hacerse con los m elementos de forma que no entran todos los elementos , no importa el orden y no se repiten los elementos. La combinación se calcula como:
[tex]C=\frac{m!}{n!*(m-n)!}[/tex]
En este caso m corresponde a las 10 ciudades en el área geográfica que va a visitar, mientras que n corresponde a las 6 ciudades que debe visitar un representante de venta durante un viaje.
Entonces:
[tex]C=\frac{10!}{6!*(10-6)!}=\frac{10!}{6!*4!}[/tex]
Considerando que el factorial ! indica que se deben multiplicar todos los números enteros y positivos que hay entre el número que aparece en la fórmula y el número 1, entonces la combinación dará como resultado:
C= 210
Hay 210 grupos diferentes de seis ciudades que el representante de ventas podrá seleccionar.
b) Se llama permutación de n elementos a cada una de las diferentes ordenaciones que se pueden hacer con esos elementos.
Si se tiene un grupo de n objetos distintos, el número de maneras diferentes que podemos tomar un número r de objetos (r < n) del grupo, está dado por la fórmula de la permutación:
[tex]P=\frac{n!}{(n-r)!}[/tex]
Si m=n para calcular el total de permutaciones se utiliza la fórmula:
P= n!
En este caso se utiliza esta última expresión, ya que se desea calcular las permutaciones de 6 ciudades en 6 posiciones:
P=6!
P=720
Hay 720 secuencias posibles existen para las seis ciudades designadas.
