Answer:
x = 3
Step-by-step explanation:
subtract 7 from both sides, then subtract 4x from both sides after
6x +7 = 4x + 13
-7 -7
6x = 4x +6
-4x -4x
2x = 6
divide both sides by 2x
answer x =3

the following graph is a linear function comparing the inches of snowfall to hours of time in a specific location.
a) what is the domain of the function? express it as an inequality
b) what is the range of the function? express it as an inequality
HELPPPP!! i really need help !
Answer:
Domain: {0 ≤ x ≤ 5}
Range: {0 ≤ y ≤ 10}
Step-by-step explanation:
The domain of any given function includes the set of all x-values that are plotted on the horizontal axis (x-axis).
The range on the other hand, includes the set of all y-values that are plotted on the vertical axis (y-axis).
The domain of the linear function plotted on the graph above includes {1, 2, 3, 4, 5}. This can be represented as an inequality as:
{0 ≤ x ≤ 5}
The range includes {2, 4, 6, 8, 10}.
This can be represented in inequality as:
{0 ≤ y ≤ 10}

1. Un edificio proyecta una sombra que mide 8 m de largo (Fig. 1.32). Se sabe que
la línea que va desde la punta de la sombra proyectada hasta el sol forma un án-
gulo de 30º con respecto del piso; y si a 1.5 m de distancia de donde termina la
sombra del edificio se alza una vara vertical (apoyada en el piso) de 50 cm de alto
cuyo extremo superior coincida con la línea mencionada:
¿Cuál es la altura del edificio?
Answer:
El edificio tiene aproximadamente 2,67 metros de altura
Step-by-step explanation:
La información proporcionada son;
La longitud de la sombra proyectada por el edificio = 8 m
El ángulo formado por la línea que va desde la punta de la sombra al Sol = 30 °
La ubicación del poste vertical desde la punta de la sombra = 1,5 m
La altura del poste vertical = 50 cm = 0,5 m
Por tanto, tenemos por triángulos semejantes formados por la punta de la sombra, la altura del poste vertical y la altura, h, del edificio la siguiente relación;
Bronceado (30 °) = h / 8 = 0,5 / 1,5
h = 8 × 0.5 / 1.5 = 8/3 m = ≈ 2.67 metros
La altura del edificio es de aproximadamente 2,67 metros.

Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Given
2 + [tex]\frac{x}{-10}[/tex] = [tex]\frac{2}{5}[/tex]
Multiply through by - 10 to clear the fractions
- 20 + x = - 4 ( add 20 to both sides )

x + 140 = 130
-140 -140
x = -10
Answer:
[tex] \huge{ \boxed{ \sf{10°}}}[/tex]
Step-by-step explanation:
x + 40 is an exterior and 130 ° is an interior angle lying to the same side of the transversal and they are not adjacent to each other. They are called corresponding angles. Remember that Corresponding angles are always equal. So now , set up an equation and solve for x.
[tex] \sf{x + 140 = 130}[/tex]
Move 140 to right hand side and change it's sign
[tex] \mapsto{ \sf{x = 130 - 140}}[/tex]
Remember: The negative and positive integer are always subtracted but posses the sign of the bigger integer.
[tex] \mapsto{ \sf{x = - 10}}[/tex]
The value of x is -10°.

Answer:
m = 123, g = 273
Step-by-step explanation:
m is the number of monkeys, g is the number of giraffes. We will use a system of equations.
m + g = 396
g = 2m + 27
Plug g into the first equation.
m + 2m + 27 = 396
Add like terms.
3m + 27 = 396
Simplify.
m = 123
Plug the value of m into the second equation
g = 2(123) + 27
Simplify
g = 273

How to know or understand easly variable which number will be in place alphabet for example, in the equation 2x + 3 = 11
Answer:
Step-by-step explanation:
a variable can have any value depending upon the equation
for example,
in 2x + 3 = 11
2x = 11 - 3
2x = 8
x = 8 / 2
x = 4
Hope this helps
plz mark as brainliest!!!!!!!
Step-by-step explanation:
Hey there!
Variables have the unknown value.
If you want to find or know value from the equation easily, you have to simply solve the equation.
For your example;
2x+3=11
Now, solve it to get value of variable 'x'.
2x = 11-3
2x = 8
[tex]x = \frac{8}{2} [/tex]
Therefore the value of variable 'x' is 4.

solve the following equation: x2-5=7
Answer:
x= 6
Step-by-step explanation:
Step 1: Write equation
2x - 5 = 7
Step 2: Solve for x
Add 5 to both sides: 2x = 12
Divide both sides by 2: x= 6
Step 3: Check
Plug in x to verify if it's a solution.
2(6) - 5 = 7
12 - 5 = 7
7 = 7

What is the multiplicative identity of the complex number -4 + 8i?
A. 0
B. 1
C. - 4 + 8i
D. 4-8i
Answer:
1
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
its 1
for those of you that don't understand, when you multiply a complex number by its multipicatuive identity, in this case -4+8i, you would multiply both the top and the bottom by -4-8i which is actually the value one since we cannot actually change the whole value of the number. By multiplying it by "1" we get the same value just without the imaginary number .
