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.

Answers

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.

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

Answers

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.

Dado dos ángulos complementarios, uno mide (2x + 10) y el otro (x + 20),

calcula el valor de x

Answers

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]

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?

Answers

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.

The area of a circle depends on the length of the radius.

What is a circle?

A circle is the locus of a point such that its distance from a fixed point known as center is always constant.

Area of a circle = π * radius²

Area of a sector = (central angle / 360) * π * radius²

To figure this out, you must use the triangle inequality theorem. It says that the sum of 2 sides of the triangle should be more than the third side. If you add 8 and 12, you get less than 24 but if you add 12 and 24 or 8 and 24, you will get more. So, there are only 2 triangles! I hope this helps!

Which choices show the ratio of the area of the smaller rectangle to the area of the larger rectangle? Select three options.

Answers

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{4}{16}=\frac{1}{4}[/tex]
