The function f(x)=-\x-4/+6 is increasing
through the interval -
A. 6
C. 4
B. -00< x < 4
D. 4
:)
Answers
Answer:
Option B
Step-by-step explanation:
Given function is,
f(x) = -|x - 4| + 6
By using a graphing tool we can get the graph of the given function.
From the graph attached slope of the line drawn from [tex]x=-\infty[/tex] to [tex]x=4[/tex] is positive while slope of the line from [tex]x=4[/tex] to [tex]x=\infty[/tex] is negative.
Therefore, segment showing a positive slope will be increasing in the given interval [tex]-\infty<x<4[/tex].
Function 'f' is increasing in the interval [tex]-\infty<x<4[/tex].
Option B will be the correct option.

Which of the following is the graph of:
(x-3)^2+(y+1)^2=9?
Answers
center = (3, -1)
radius = 3
==================================================
Explanation:
Rewrite the y+1 as y-(-1). Rewrite the 9 as 3^2
Then compare to the general form (x-h)^2+(y-k)^2 = r^2
You should find that h = 3, k = -1 and r = 3.
The center is (h, k) = (3,-1) and the radius is r = 3.

Un estudiante debe recorrer dos tercios de kilómetro para llegar al colegio, si avanza medio kilómetro en bus y lo demás a pie ¿Cuánto le falta caminar?
Answers
Answer:
Al estudiante le falta caminar [tex]\frac{1}{3}[/tex] de kilómetro.
Step-by-step explanation:
Un estudiante debe recorrer dos tercios de kilómetro para llegar al colegio. Dos tercios equivale a la fracción [tex]\frac{2}{3}[/tex] .
El estudiante avanza medio kilómetro en bus. Un medio equivale a la fracción [tex]\frac{1}{2}[/tex], por lo tanto un medio es la mitad de una cantidad. Para calcular la distancia recorrida en bus se realiza la siguiente multiplicación:
[tex]\frac{1}{2} *\frac{2}{3}[/tex]
Resolviendo:
[tex]\frac{1}{2} *\frac{2}{3} =\frac{1*2}{2*3} =\frac{2}{6} =\frac{1}{3}[/tex]
Entonces, la distancia recorrida en bus es [tex]\frac{1}{3}[/tex] de kilómetro.
Para calcular la distancia recorrida a pie se calcula la diferencia entre la distancia total a recorrer por el estudiante y la distancia recorrida en bus. Esto es:
[tex]\frac{2}{3} - \frac{1}{3}[/tex]
Resolviendo:
[tex]\frac{2}{3} - \frac{1}{3}=\frac{2-1}{3} =\frac{1}{3}[/tex]
Al estudiante le falta caminar [tex]\frac{1}{3}[/tex] de kilómetro.

Answers
Answer:
height = (area x 2) / sum of bases
18.29 inches
Step-by-step explanation:

When you hear that a TV is 40 inches, the length from one corner to the opposite corner diagonally is 40 inches. To solve, we use formula for hypotenuse, a^2 + b^2 = c^2.
20^2 + 25^2 = 32.02^2.
If that is what they mean by size, your answer is 32.02. However, size could refer to the area of the screen, which is calculated by length * width.

vertex = (3, -4)y intercept = (0, 5)x intercepts = (1, 0) and (5, 0)axis of symmetry: x = 3========================================================
Explanation:
The vertex is the lowest point for parabolas that open upward like this. The lowest point is (3, -4). If the parabola is flipped upside down, then the vertex would be the highest point.
--------
The y intercept is where the graph crosses the y axis. For any function, it will have at most one y intercept (some don't have any at all but the most you can have is 1 y intercept). The graph crosses the vertical y axis at (0,5). We can say in short "the y intercept is 5". The y intercept always occurs when x = 0.
--------
On the flip side, the x intercept always occurs when y = 0. This is where the graph crosses or touches the x axis. We have two such locations of (1,0) and (5,0). In short, we could say "the x intercepts are 1 and 5". The term "root" is another word we could use in place for "x intercept". Unlike the y intercept, we can have as many x intercepts as we want.
--------
The axis of symmetry is the vertical line through the parabola. It is the x coordinate of the vertex. So it's not a coincidence that the vertex is at (3,-4) and the axis of symmetry is x = 3, with those '3's repeated twice.

Answer:
x = 16
Step-by-step explanation:
We know that the 2 given angles are same side interior angles, and therefore are supplementary (add up to 180°). The equation to solve for "x" would be written as:
(Angle 1) + (Angle 2) = 180°
(8x - 10) + (62) = 180°
8x + 52 = 180
8x = 180 - 52
8x = 128
x = 16
Therefore, x = 16

Part 1: What percent of the eligible students voted for Carlos?
Part 2: How many votes did LaToya receive?
Part 3: How many votes did Stepanie recieve?
Part 4: Who won the election?
Answers
Answer:
Part 1) 30%
Part 2) 80 students
Part 3) 57 votes
Part 4) LaToya
Step-by-step explanation:
75 divided by 250 = 0.30 = 30%
32% = 0.32 and then 0.32 times 250 = 80 students
250 - 75 - 80 = 95 students that didn't vote for Carlos or LaToya. Then 0.60 times 95 = 57
LaToya had 80 votes, the most votes.

Answer Choice 1. Incorrect. Minerals can be found all over the world in the crust of the earth, but generally in such small quantities that they are not worth extracting.
Answer Choice 2. Correct. Fossil fuels can be found more in areas that had a lot of plant growth because, after a long time, the heat and pressure changed the plants into fossil fuels.
Answer Choice 3. Incorrect. Minerals, fresh water, and biosphere resources are distributed unevenly around the planet as a result of past geologic processes.

5x - 7 = 2x + 11
x = ?
Answers
Answer:
6
Step-by-step explanation:
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
-7 + 5x + -2x = 11 + 2x + -2x
Combine like terms: 5x + -2x = 3x
-7 + 3x = 11 + 2x + -2x
Combine like terms: 2x + -2x = 0
-7 + 3x = 11 + 0
-7 + 3x = 11
Add '7' to each side of the equation.
-7 + 7 + 3x = 11 + 7
Combine like terms: -7 + 7 = 0
0 + 3x = 11 + 7
3x = 11 + 7
Combine like terms: 11 + 7 = 18
3x = 18
Divide each side by '3'.
x = 6
Simplifying
x = 6
Answer:
x=6
Step-by-step explanation:
Solve 5x−7=2x+11.
Subtract 2x from both sides.
5x−7−2x=2x+11−2x
3x−7=11
Add 7 to both sides.
3x−7+7=11+7
3x=18
Divide both sides by 3.

En un acuario compraron 30 peces y 18 tortugas de agua. Los van a colocar en peceras. Cada una tiene que haber la misma cantidad de peces, la misma cantidad de tortugas y la mayor cantidad de animales posibles ¿cuantas peceras compraron? ¿cuantos peces compraron? ¿cuantos peces y tortugas puede tener cada pecera? Diganme porfaa
Answers
Answer:
a) ¿Cuántas peceras compraron?
Según el cálculo anterior, la cantidad de peceras que compró es de 90 peceras.
b) ¿Cuántos peces y tortugas puede tener cada tanque?
3 peces por tanque
5 tortugas de agua por tanque
Step-by-step explanation:
Resolvemos la pregunta anterior utilizando el cálculo de múltiplo común más bajo
En un acuario compraron 30 peces y 18 tortugas de agua.
Encuentre y enumere los múltiplos de cada número hasta encontrar el primer múltiplo común. Este es el mínimo común múltiplo.
El mínimo común múltiplo es el número de tanques
Múltiplos de 18:
18, 36, 54, 72, 90, 108, 126
Múltiplos de 30:
30, 60, 90, 120, 150
Por lo tanto,
MCM (18; 30) = 90
a) ¿Cuántas peceras compraron?
Según el cálculo anterior, la cantidad de peceras que compró es de 90 peceras.
b) ¿Cuántos peces y tortugas puede tener cada tanque?
El número de peces que puede tener cada tanque = Número de tanques / Número de peces
= 90/30
= 3 peces por tanque
El número de tortugas de agua que puede tener cada tanque =
Número de tanques / Número de tortugas de agua
= 90/18
= 5 tortugas de agua por tanque
