Step-by-step explanation:
Okay so remember the BODMAS rule where u start with brackets right; Since we're proving that RHS =LHS ,we look at the side which is more complicated and solve it first.
RHS: -4a-(8a+1) =-169
-4a-8a-1=-169
-4a-8a= -169+1 ( N:B like terms)
-12a= -168
-12a/-12= -168/-12
a= 14
Then go back to the original equation and subtitute .
where u see a u put the value u calculated.
-4a-(8a+1)=-169
-4(14)-(8(14)+1)= -169
-169= -169 and u DONE!!

Answer:
208
Step-by-step explanation:
First term = a = 4
Common difference = d = a2 - a1 = 9 - 3 = 6
35th term = a + (35 - 1)d
4 + (35 - 1)6
4 + (34)6

two numbers have a sum of 25. if one number is x, represent the other number as an expression in x
write as a algebraic expression plz like asap
Answer:
x+n
Step-by-step explanation:
The expression for another number will be 25 - x.
What is an expression?An expression is a combination of some mathematical symbol such that arithmetic operator and variable such that all are constrained and create an equation.
In other meaning, expression is very useful to determine the end or root value of constraint.
For example 3x +5y
The constraint of expression is represented as = or <, >.
Let's say another number is y
Then,
Sum of both number
x + y = 25
y = 25 - x
Hence "The expression for another number will be 25 - x".

Kiara desea contratar el servicio de una línea telefónica con internet para realizar sus clases virtuales. Si el costo de una línea de telefonía móvil con Internet es C = 10 + 1,5t (C, en soles; t, en horas).
- Expresa el costo de la línea telefónica móvil en función del tiempo.
- Determina el dominio y el rango de una función.
- ¿Cuál será el costo luego de 48 horas de consumo de la línea telefónica con Internet?
Doy coronita
a) Kiara ha adquirido una línea de telefonía móvil con internet a un Coste Fijo de 10 soles y un Tasa de Consumo de 1,5 soles por hora consumida.
b) El Coste total por 48 horas de consumo de la línea telefónica con internet es 82 soles.
a) Nota - Puesto que la ecuación que describe el Coste ya existe en el enunciado, entonces se entiende el verbo "Expresa" como "Describa en sus propias palabras".
Como puede apreciarse el Coste de la línea telefónica móvil aumenta linealmente con el Tiempo de consumo por parte del usuario. En consecuencia, la función de Coste queda definida como sigue:
[tex]C(t) = C_{o} + r\cdot t[/tex] (1)
Donde:
[tex]C_{o}[/tex] - Coste fijo, en soles.[tex]r[/tex] - Tasa de consumo, en soles por hora.Entonces, tenemos que Kiara ha adquirido una línea de telefonía móvil con internet a un Coste Fijo de 10 soles y un Tasa de Consumo de 1,5 soles por hora consumida.
b) Una característica de las Funciones Lineales es que tanto su Dominio como Rango comprenden al Conjunto de todos los Números Reales, al ser de Pendiente constante esta Función.
Por tanto, el Dominio y el Rango de la Función en cuestión es el Conjunto de todos los Números Reales.
c) Si sabemos que [tex]C_{o} = 10[/tex], [tex]r = 1,5[/tex] y [tex]t = 48[/tex], entonces el Coste Total por concepto de 48 horas de consumo es:
[tex]C(48) = 10 + 1,5\cdot (48)[/tex]
[tex]C(48) = 82[/tex]
El Coste total por 48 horas de consumo de la línea telefónica con internet es 82 soles.

Find the slope of the line whose equation is 8 y = 4 − 3 x .
Answer:
-3/8
Step-by-step explanation:
8y = 4 - 3x
~Divide 8 to everything
y = 1/2 - 3/8x
~Reorder
y = -3/8x + 1/2
In slope intercept form [ y = mx + b ] m resembles the slope so -3/8 is the slope.

4. Line segment CD is the perpendicular bisector of line
segment AB. Is line segment AB the perpendicular
bisector of line segment CD?
The line AB is not a perpendicular bisector of CD.
Perpendicular bisectors are lines that divides another line into two equal parts.
From the diagram, we can see that line CD cuts AB at the centre. Hence we can say that CD is a perpendicular bisector of AB.
The same is not applicable to line AB passing through CD. The line AB did not bisect (divide equally) line CD.
Hence we can conclude that line AB is not a perpendicular bisector of CD.

two members have a sum of 112. If one number is x, represent the other numbers as an expression in x
Based on the information given, the other number will be 112 - x
Value of the first number = x
Value of the second number = y
Sum of the numbers = 112
Therefore, the value of the second number will be:
x + y = 112
y = 112 - x
In conclusion, the value of the second number is 112 - x.

A = -8
B = 27
X = 6
y = 3
z = 9
Step-by-step explanation:
hope that helps
Answer:
Below in bold.
Step-by-step explanation:
A = (-2)^3 = -8.
B = (3)^3 = 27.
j^(3*3) = j^9 and j^(1*3) = j^3
j^9 / j^3 = j^6
So x = 6.
y = 3.
m^(3 * 3) = m^9.
z = 3*3 = 9.
How many Christmas trees were sold on sat and sunday?
Hello :D
Let's form an equation:
x/5 = 27
Let's form another equation:
(x+y)/7 = 34
Rearrange equation one so it is x = 27 x 5 = 135
Now we can substitute this value into equation 2:
(135 + y)/7 = 34
135 + y = 238
y = 238 - 135
y = 103
Answer is 103
Answer:
103 christmas trees.
Step-by-step explanation:
total trees sold in the first five days:

Answer:
The first box (upper left corner)
Step-by-step explanation:
Since the y-intercept is 1/4 (you can find this where x = 0), in slope intercept the second number must equal the y-intercept.
Example:
y = 3x + 2 (0,2) is the y-intercept.
Therefore, the second number must equal 1/4 which the first box is correct.
(Negative 1/4 multiplied by -1 equals positive 1/4)
