Ecuacion de la recta que pasa por el punto donde se cortan las rectas X+4Y=0 y X-3Y-7=0 y que tiene como pendiente -6
Answer:
La ecuación de la recta es [tex]y = -6\cdot x +23[/tex].
Step-by-step explanation:
Para construir la ecuación de la recta podemos utilizar un punto contenido en la recta y su pendiente. En primer punto, hallamos el punto con la resolución del siguiente sistema de ecuaciones lineales:
[tex]x+4\cdot y = 0[/tex] (1)
[tex]x-3\cdot y = 7[/tex] (2)
La solución del sistema de ecuaciones es [tex](x,y) = (4,-1)[/tex].
Por Geometría Analítica, sabemos que la Ecuación de la Recta en su forma explícita es:
[tex]y = m\cdot x + b[/tex] (3)
Donde:
[tex]x[/tex] - Variable independiente.
[tex]y[/tex] - Variable dependiente.
[tex]m[/tex] - Pendiente.
[tex]b[/tex] - Intercepto.
Si sabemos que [tex](x,y) = (4,-1)[/tex] y [tex]m = -6[/tex], entonces el intercepto de la recta es:
[tex]b = y-m\cdot x[/tex]
[tex]b = 23[/tex]
Ahora, la ecuación de la recta es [tex]y = -6\cdot x +23[/tex].

What is the domain of the function shown on the graph?
Answer:
B. negative infinity < x < positive infinity
Step-by-step explanation:
When a question asks for the domain of a function, it is asking for all possible x-values, so we can rule out choice A since there are clearly x-values greater than 1. This graph shows arrows pointing left and downward, indicating that the graph continues past what we can see. This tells us that even though the x-values look like they end at -10 and 2, they continue further, so we can also rule out option C and option D. After these eliminations, we are left with choice B, which is a way of writing "All real numbers," and is the domain for all exponential functions, including this one.

A because you can go into the numbers evenly
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
it is important to note that 40/8 = 5.
A real number is one that can be found on the number line, and 5 can be.
A rational number can be made by dividing two integers (40 by 8 in this case).
5 is a whole number since it does not have a decimal/fractional part
an integer is a whole number which is positive/negative (5 is positive in this case)

Find the radius of a circle that has a circumference of 16
The formula for the circumference of a circle is C = 2.
where r is the radius and C is the circumference. The
TE
equation solved for r is r =
27
O r=4
O r= 8
O r= 12
O r= 16
Answer:
The circumference of a circle is equal to π , which is a number ≈3.14 , multiplied by the diameter of the circle. Therefore ... We also know that the diameter has twice the length of the radius. In equation form: 2r=d. 2r=16. r=8. Note that since 2r=d , the equation C=2πr holds and can be used in place of C=πd .

Answer:
∠RPQ = 53°
Step-by-step explanation:
∠SPR and ∠RPQ are complementary, meaning that they add up to 90°. So,
∠SPR + ∠RPQ = 90°
We know that ∠SPR = 37°, so
37° + ∠RPQ = 90°
∠RPQ = 90° - 37°
∠RPQ = 53°
Tony and Edwin each built a rectangular garden. Tony's garden is 4 feet longer and 5 feet wider than Edwin's garden. If the perimeter of Edwin's garden is 36 feet, what is the perimeter of Tony's garden?
Answer:
54 feet
Step-by-step explanation:
Perimeter of a rectangle = 2 × (length + breadth)
The perimeter of Edwin's garden is 36 feet :
36 = 2 x (length + breadth)
divide both sides by 2 to determine the sum of the length and breadth of Edwin's garden
36/2 = (length + breadth)
18 = (length + breadth)
Tony's garden is 4 feet longer and 5 feet wider than Edwin's garden
The dimensions of Tony's garden is :
(4 + l) + (5 + w) = 9 + l + w
Where :
l = length
w = width
The sum of the length and breadth of Tony's garden would be 9 feet more than that of Edwin
Sum of Edwin's garden = 9 + 18 = 27
Perimeter of Edwin's garden = 27 feet x 2 = 54 feet
Elena would like to know the average height of seventh graders in her school district. She measures the heights of everyone in a random sample of 20 students. The mean height of Elena's sample is 58 inches, and the MAD (mean absolute deviation) is 3 inches. Select all the true statements. The mean height of all seventh graders is likely be between 52 and 64 inches. Another random sample of 20 students will always have a mean of 58 inches. A sample of 20 female students would be more likely to get an accurate estimate of the mean height of the population than a sample of a mix of 20 male and female students. m A sample of 100 seventh graders would be more likely to get an accurate estimate of the mean height of the population than a sample of 20 seventh graders. a Elena's sample proves that half of all seventh graders are taller than 58 inches.
Answer:
A. The median height of the sample must be between 59 and 63 inches.
B. Another random sample of 20 students is likely to have a mean between 57 and 65 inches.
E. Elena would be more likely to get an accurate estimate of the mean height of the population by sampling 40 people instead of sampling 20 people.
Step-by-step explanation:
The mean absolute deviation shows the variation in a given data set. It can be determined by calculating the mean of the absolute value of the initial mean and each data set. It describes how spread out the data set are.
With respect to Elena's sampling, the mean absolute deviation is 2. This shows that there is little variation among the data set.
The estimate becomes more accurate if she increase the sample size. Thus options A, B and E are appropriate.

a:30
b:40
c:45
d:50
e:60
Answer:
B
Step-by-step explanation:
if you multiply m by 2 you get 260we now want to subtract this from 360 to get 100 then we divide that by 2 to get angle n∠BEF= 50°.
We know angle k∠EBF= 90° so we now end up with adding angle ∠BEF with ∠EBF to get 140 to get angle x we subtract 140 from 180 to get 40. x=40°. so B is the correct answer
