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°.
Hope I helped!
Best regards! :D

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 .

1. A local bakery has a daily operating cost of $1800 plus a cost of $10 per cake they make. If a cake sells for $15, which equation could be used to determine the minimum number of cakes, c, they must sell each day to earn a profit?
20 points
A 15c 1800 + 10c
C 10c 1800 + 15c
Answer:
C.) 10c 1800+15c
Step-by-step explanation:
The cost of daily operation for the business is $1,800/day, and $10/cake made. To put this into an equation, put the expenses on one side and what you're trying to make a profit off of on the other. Then solve for c.
the cost of 25 pounds of dog food is $56.50. What is the cost for 6 pounds of dog food
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.

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
Can someone help me please
Answer:
f(n)= 160 -80n
Step-by-step explanation:
f(n)= 160 - 80n
the start is 160 you keep subtracting 80 depending on N so if N were 10 then you would do 160 - 80 *10 = 160 - 800 = -640
please help!!! i don't need an explanation, and its due pretty soon !
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
i need to find g for this equation 2g−13=3.
Answer:
13
Step-by-step explanation:
Step 1:
2g - 13 = 3 Equation
Step 2:
2g = 26 Add 13 on both sides
Step 3:
26 ÷ 2 Divide
Answer:
g = 13

Step-by-step explanation:
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}
