Answer:
b = -4
Step-by-step explanation:
your equation: -4b + 2 = 18
subtract 2 from both sides: -4b = 16
divide both sides by -4 to isolate the variable: b = -4
Answer:
b= -4b=18-2
=16
b=16+(-4)
=12

2 rectas se cortan formando 4 ángulos iguales ¿cuanto mide cada uno?
Answer:
Cada ángulo igual es recto, es decir, mide 90°
Step-by-step explanation:
Intersección de dos rectas
Cuando dos rectas no paralelas se intersectan, forman en el punto de corte 4 ángulos iguales de a pares, es decir, dos pares de ángulos congruentes.
La suma de todos los ángulos formados es invariablemente 360°.
En general, siendo a y b dos ángulos adyacentes formados por el cruce, se cumple que:
a + b = 180°
Y la suma de todos los ángulos es el doble de lo anterior:
2a + 2b = 360°
Si todos los ángulos son iguales, a=b, entonces:
4a = 360°
a = 90°
Cada ángulo igual es recto, es decir, mide 90°

The pattern of numbers below is an arithmetic sequence:
14, 24, 34, 44, 54, ...
Which statement describes the recursive function used to generate the sequence?
The common difference is 1, so the function is f(n + 1) = f(n) + 1 where f(1) = 14.
The common difference is 4, so the function is f(n + 1) = f(n) + 4 where f(1) = 10.
The common difference is 10, so the function is f(n + 1) = f(n) + 10 where f(1) = 14.
The common difference is 14, so the function is f(n + 1) = f(n) + 14 where f(1) = 10.
Answer:
The common difference is 4, so the function is f(n + 1) = f(n) + 4 where f(1) = 10.
Step-by-step explanation:
14 + 10 = 24
24 + 10 = 34
34 + 10 = 44
44 + 10 = 54
54 + 10 = 64

PLEASE HELP!!!!! 2.) What is the perimeter of a polygon with vertices at (-3, 1), (5, 1), (-3, 4), (5, 4)? 30 points if you can help
Answer:
22 units.
Step-by-step explanation:
We want to find the perimeter of the polygon with vertices at: (-3, 1); (5, 1); (-3, 4); and (5, 4).
Let’s first plot the points and see what polygon we acquire. Please refer to the graph below.
As we can see, when plotting the points and connecting them, we get a rectangle.
So, we can use the perimeter formula for a rectangle, given by:
[tex]P=2(\ell+w)[/tex]
Where [tex]\ell[/tex] Is the length and [tex]w[/tex] is width.
Remember that the perimeter is simply the distance around the figure.
So, let’s find the length. We can do so by counting or by subtracting.
By counting, we can see that the length (longer side) is 8 units.
And by subtracting, we get the same length of |5-(-3)| or 8 units.
We use absolute value because distance is always positive.
Using the same process, we find the width to be 3 units.
Using subtract, we can see that this is indeed true as |1-4|=3.
So, we can now substitute the values into our formula:
[tex]P=2(8+3)[/tex]
Evaluate:
[tex]P=2(8+3)=2(11)=22\text{ units}[/tex]
So, the perimeter of the polygon is 22 units.
