Solve -2/3n<16 which of the following must be true about the inequality and the resulting graph? Select three options.
A. n < -24
B. n > -24
C. The circle is open
D. The circle is closed
E. The arrow points right.
Answer:
n > -24 The circle is open. The arrow points right.
Step-by-step explanation:
To solve for n, divide both sides by -2/3.
When you divide an inequality by a negative number, reverse the inequality.
Here < becomes >.
Dividing by a fraction is done by multiplying by its reciprocal.
16 ÷ -2/3 becomes 16 × -3/2. That's -24.
The open circle means not equal to.
n is all the numbers greater than -24, so the arrow points right.

For two functions, m(x) and p(x), a statement is made that m(x) = p(x) at x = 7. What is definitely true about x = 7? (2 points)
Both m(x) and p(x) cross the x-axis at 7.
Both m(x) and p(x) cross the y-axis at 7.
Both m(x) and p(x) have the same output value at x = 7.
Both m(x) and p(x) have a maximum or minimum value at x = 7.
Answer:
Both m(x) and p(x) have the same output value at x = 7
Step-by-step explanation:
for two functions m(x) and p(x) we know that the solution to the equation :
m(x)=p(x) is the x-value of the point of intersection of the two curves.
i.e. at this point the output value i.e. the value which is obtained on putting the input value i.e. 'x' is same for the two functions m(x) and p(x).
Hope This Helped
When m(x) = p(x) at x = 7, it implies that both functions produce the same output value at x = 7, representing the equality of the functions.
Both m(x) and p(x) have the same output value at x = 7. When m(x) = p(x) at x = 7, it means that both functions produce the same output value at x = 7. This is the defining characteristic of the statement made.
For a given x value of 7, both m(x) and p(x) will yield an identical result, indicating that they are equal at that specific point. This does not necessarily mean they cross the x-axis, y-axis, or have maximum or minimum values at x = 7, but rather that their outputs are the same at this particular x value.
Therefore, the correct statement about x = 7 when m(x) = p(x) is that both m(x) and p(x) have the same output value at x = 7.

If AB = 9, RS = 3, and SC = 5, find BC.
A) 5
B) 10
C) 13.5
D) 15
Answer:
D
Step-by-step explanation:
Δ ABC and Δ RSC are similar triangles, thus the ratio of corresponding sides are equal, that is
[tex]\frac{BC}{SC}[/tex] = [tex]\frac{AB}{RS}[/tex], substitute values
[tex]\frac{BC}{5}[/tex] = [tex]\frac{9}{3}[/tex] = 3 ( multiply both sides by 5 )
BC = 5 × 3 = 15 → D
Answer:
BC=15, so D
Step-by-step explanation:
First, let's annotate. on line AB, write 9. RS, 3. SC, 5. These are the measurements of lines, not angles. We're trying to find the length of BC, the whole bottom side. Also, all of the little squares represent 90° angles, which means the triangles are also rational.
Lengths 3 and 9 are rational. 1:3. Since they're rational, the triangles are a set of dilations. Because of this, ALL the sides of the triangles are rational. If all the sides are rational by 1:3, which they are, then we can just multiply SC by 3. By doing this, we get the length of BC. Thus, the length of BC is 15.I REALLY hope this helps. If not, I encourage you to watch videos on dilations/rational triangles.
two people were doing yard work for 1 hour and 35 minutes then they stopped for lunch at 1:20pm at what time did they start doing yard work?
Answer: The answer would be at 11:45.
Step-by-step explanation: First I though, if they stoppedd for lunch at 1:20 and they've been doing yard work for 1 hour and 35 minutes, I would subtract. 1 hour taken away from 1:20 would be 12:20. Then, since it would be hard to subtract 35 minutes from 12:20, 35 minutes - 20 minutes = 15 minutes. 12:20 subtract 20 minutes = 12:00. 12:00 - 15 minutes equal to 11:45. I hope this helps. I know this explanation can be confusing but it's the best I can do at the moment.

At the positive integer value of x=7 the quadratic function begin to exceed the linear function
Step-by-step explanation:
The positive difference between the maximums of functions g and f is 2
What is the positive difference between the maximums of functions g and f?From the question, we have the following parameters that can be used in our computation:
f(x) = -x² + 4x + 6
So, the x of the vertex is
x = -4/2 * -1
x = 2
So, the maximum is
Max = -2² + 4(2) + 6
Max = 10
From the graoh, we have
Max = 12
So, we have
Difference = 12 - 10
Difference = 2
Hence, the positive difference is 2

How many pints of water will the aquarium hold? (to a tenth of a pint)
A) 33.6 pints
B) 67.2 pints
C) 134.4 pints
D) 268.8 pints
Answer:
Both are C.
Step-by-step explanation:
16.8 gallons of water is equal to 67.2 quarts and 134.4 pints.
Final answer:
To convert gallons to quarts, multiply the number of gallons by 4, which gives us 67.2 quarts (Option C). To convert gallons to pints, multiply the number of gallons by 8, resulting in 134.4 pints (Option C).
Explanation:
The question pertains to converting units of volume from gallons to quarts and pints. Given that the aquarium has a capacity of 16.8 gallons and knowing that there are 4 quarts in a gallon, we multiply 16.8 by 4 to find the capacity in quarts:
16.8 gallons × 4 quarts/gallon = 67.2 quarts
Next, to find the number of pints, we consider that there are 8 pints in a gallon (since each quart is equivalent to 2 pints, and there are 4 quarts in a gallon). Thus, we multiply:
16.8 gallons × 8 pints/gallon = 134.4 pints

Answer:
The options b) ,c) and e) are correctThe three choices shows the ratio of the area of the smaller rectangle to the area of the larger rectangle are b)[tex](\frac{4}{16})^2[/tex] , c) [tex]\frac{12}{192}[/tex] and e) [tex](\frac{3}{12})^2[/tex]Step-by-step explanation:
Given that a large rectangle has a length of 16 and width of 12.
A smaller rectangle has length of 4 and width of 3
To show the ratio of the area of the smaller rectangle to the area of the larger rectangle:we know that "If two figures are similar, the the ratio of its areas is equal to the scale factor squared"
From the given scale factor is [tex]\frac{1}{4}[/tex]
Let z be the scale factor
Let x be the area of the smaller rectangle
Let y be the area of the large rectangle
[tex]z^2=\frac{x}{y}[/tex]
Since scale factor is [tex]\frac{1}{4}[/tex] hence [tex]z=\frac{1}{4}[/tex]
we have [tex]z^2=(\frac{1}{4})^2[/tex]
[tex]=\frac{1}{16}[/tex]
∴ [tex]z^2=\frac{1}{16}[/tex]
Now show that the ratio of the area of the smaller rectangle to the area of the larger rectangle with each options.
a) [tex]\frac{4}{16}[/tex]

[tex]\frac{1}{16}=\frac{1}{16}[/tex]
This implies that the ratio of the area of the smaller rectangle to the area of the larger rectangle.c) [tex]\frac{12}{192}[/tex]

Write an equation in slope-intercept form of the line with the given parametric equations,
x = 8t+3
y= 9t+3
The equation in slope-intercept from is y = [tex]\frac{9}{8}x - \frac{3}{8}[/tex].
Step-by-step explanation:
Given,
x = 8t+3
y= 9t+3
First, convert both the equations in terms of t for comparison.
x = 8t + 3
x - 3 = 8t
t = [tex]\frac{x-3}{8}[/tex]
Similarly,
y = 9t + 3
y - 3 = 9t
t = [tex]\frac{y-3}{9}[/tex]
Now, comparing both equations
[tex]\frac{x-3}{8}[/tex] = [tex]\frac{y-3}{9}[/tex]
9x -27 = 8y -24
9x - 3 = 8y
or
y = [tex]\frac{9}{8}x - \frac{3}{8}[/tex]
Hence, the equation in slope-intercept from is y = [tex]\frac{9}{8}x - \frac{3}{8}[/tex].

Dado dos ángulos complementarios, uno mide (2x + 10) y el otro (x + 20),
calcula el valor de x
Answer:
El valor de x es igual a 20 o x = 20.
Step-by-step explanation:
Lo primero que se debe saber es que dos ángulos complementarios suman un ángulo recto o 90º.
Supongamos que el valor de un ángulo [tex] \\ \alpha[/tex] y un ángulo [tex] \\ \beta[/tex] valen:
[tex] \\ \alpha = 2x + 10[/tex] [1]
[tex] \\ \beta = x + 20[/tex] [2]
Como la suma de [tex] \\ \alpha + \beta = 90[/tex] [3]
Entonces
[tex] \\ \alpha + \beta = (2x + 10) + (x + 20) = 90[/tex]
Sumamos los factores comunes entre si:
[tex] \\ (2x + x) + (10 + 20) = 90[/tex]
Para la primera expresión debemos recordar que se suman sólo los coeficientes. Así:
[tex] \\ (2 + 1)x + (10 + 20) = 90[/tex]
[tex] \\ 3x + 30 = 90[/tex]
Para despejar la incógnita x, debemos tener en cuenta que una igualdad no se altera si se suma, se resta, se multiplica o divide un mismo valor a cada lado de ella. Por esta razón, para despejar 3x, lo primero que podemos hacer es sumar -30 a cada lado de la expresión (lo que es igual a restar 30 a cada lado de la misma). Así tenemos:
[tex] \\ 3x + 30 - 30 = 90 - 30[/tex]
[tex] \\ 3x + 0 = 90 - 30[/tex]
[tex] \\ 3x = 60[/tex]
Ahora dividimos cada miembro de la igualdad entre 3 (o multiplicamos cada lado de la igualdad por [tex] \\ \frac{1}{3}[/tex] ):
[tex] \\ \frac{3}{3}x = \frac{60}{3}[/tex]
Como sabemos que:
[tex] \\ \frac{3}{3} = 1[/tex]
Entonces:
[tex] \\ 1*x = \frac{60}{3}[/tex]
[tex] \\ x = \frac{60}{3}[/tex]
[tex] \\ x = 20[/tex]
De esta manera, el valor de x es igual a 20 o x = 20.
Lo anterior lo podemos comprobar considerando las ecuaciones [1], [2] y [3]. Así tenemos que:
[tex] \\ \alpha = 2x + 10[/tex] [1]
Sustituimos x por el valor de 20:
[tex] \\ \alpha = 2*20 + 10 = 40 + 10 = 50[/tex]
[tex] \\ \beta = x + 20[/tex] [2]
Hacemos lo mismo para [2]:
[tex] \\ \beta = 20 + 20[/tex]
[tex] \\ \beta = 40[/tex]
De esta manera:
[tex] \\ \alpha + \beta = 90[/tex] [3]
[tex] \\ 50 + 40 = 90[/tex]

What is the solution to the system of equations 2x + 3y = 40 and y = x + 10?
x = 2; y = 12
x = 4; y = 14
x = 12; y = 2
x = 14; y = 4
Answer:
x=2, y=12
STEP BY STEP-
Replace the Y in 2x+3y=40 for X+10, because y=x+10. You now have 2x+3(x+10)=40. Now multiply the X and the 10 by 3, so you have 2x+3x+30=40. Combine like terms to get 5x+30=40. Subtract the 30 on both sides so you get 5x=10. Divide by 5 and that gives you the solution for X (2). Then, plug 2 in for X in the equation y=x+10. You now have Y=2+10. Combine like terms and you get 12, so Y=12.
Sorry that I'm so bad at explaining things
Final answer:
Substitute y = x + 10 into 2x + 3y = 40, simplify to 5x = 10, solve for x, then substitute x into the second equation to find y. The solution is x = 2 and y = 12.
Explanation:
The solution to the system of equations 2x + 3y = 40 and y = x + 10 can be found by substituting the second equation into the first. This is a common method for solving systems of linear equations, which involves elimination and substitution. We substitute y from the second equation into the first to get 2x + 3(x + 10) = 40, which simplifies to 2x + 3x + 30 = 40. After combining like terms, we have 5x = 10, which gives us x = 2. We then substitute x back into the second equation to find y. If x = 2, then y = 2 + 10, which means y = 12.

A circle with diameter 8 centimeters.
The diameter is 8 cm and the radius is 16 cm.
The circumference of the circle in terms of Pi is 8 pi.
If Pi is approximated to StartFraction 22 over 7 EndFraction, the circumference of the circle is approximately 25.14 cm.
The circumference of the circle rounded to the nearest whole number is 20 cm.
If Pi is approximated to 3.14, the circumference of the circle is 25.12 cm.
Answer:
The circumference of the circle in terms of π is 8π.
If π is approximated to 22/7, the circumference of the circle is approximately 25.14 cm.
If π is approximated to 3.14, the circumference of the circle is 25.12 cm.
Step-by-step explanation:
The circumference of the circle = 2*π*r
r = radius
r = d/2
r= 8cm/2 = 4cm
π = 3.14
The circumference of the circle = 2π(4)= 8π , so we have:
The circumference of the circle in terms of π is 8π.
Using pi = 22/7, we have:
The circumference of the circle = 2* 22/7 * 4 = 8* 22/7 = 25.14 cm, so we have:
If π is approximated to 22/7, the circumference of the circle is approximately 25.14 cm.
Using pi = 3.14, we have:
The circumference of the circle = 2* 3.14 * 4 = 8* 3.14 = 25.12 cm, so we have:
If π is approximated to 3.14, the circumference of the circle is 25.12 cm.
Here we want to see which statement is correct about a circle with a diameter of 8cm.
The correct options are
"The circumference of the circle in terms of Pi is 8 pi.""If Pi is approximated to StartFraction 22 over 7 EndFraction, the circumference of the circle is approximately 25.14 cm.""If Pi is approximated to 3.14, the circumference of the circle is 25.12 cm."Things that we must know about circles:
We know that for a circle of diameter D:
The radius is half the diameter, so R = D/2The circumference is pi times the diameter, so C = pi*DThe area is pi times the radius squared: A = pi*R^2So our circle of diameter of 8cm has:
Radius R = 8cm/2 = 4cmCircumference C = pi*8cm = 3.14*8cm = 25.12cmArea A = pi*(4cm)^2 = pi*16cm^2And if pi = 22/7, the circumference is:
C = (22/7)*8cm = 25.14cm
Then the correct statements are:
"The circumference of the circle in terms of Pi is 8 pi.""If Pi is approximated to StartFraction 22 over 7 EndFraction, the circumference of the circle is approximately 25.14 cm.""If Pi is approximated to 3.14, the circumference of the circle is 25.12 cm."If you want to learn more about circles, you can read:
