Answer:

El perímetro y el área de un rectángulo cuyos lados miden 6,3 dm y 48 cm es 222 cm y 3024 cm² respectivamente.

Step-by-step explanation:

Para empezar debes tener en cuenta que las medidas tienen que estar en la misma magnitud; por lo tanto en este caso la unidad de medida elegida a utilizar es centímetros. Por lo que el lado que mide 6,3 dm será expresado en cm. Entonces se puede aplicar la siguiente regla de tres simple: si 1 dm equivale a 10 cm, entonces 6,3 dm a cuántos cm equivale?

[tex]cm=\frac{6,3 dm*10 cm}{1 dm}[/tex]

cm=63

Entonces 6,3 dm= 63 cm

El perímetro es la distancia alrededor de una figura, mientras que el área es las unidades cuadradas dentro de una figura.

El Perímetro de un rectángulo es igual a la suma de todos sus cuatro lados.  Un rectángulo siempre tiene dos pares de longitudes iguales. Entonces en este caso se obtiene:

63 cm + 63 cm + 48 cm + 48 cm= 222 cm

El área de un rectángulo es el producto de la longitud de los lados. Entonces en este caso se obtiene:

63 cm* 48 cm= 3024 cm²

El perímetro y el área de un rectángulo cuyos lados miden 6,3 dm y 48 cm es 222 cm y 3024 cm² respectivamente.

Answer:

3 hours

Step-by-step explanation:

The equation will be

10b+25t ≤ 130 (b = hours of babysitting, t = hours of tutoring)

Plug in the 4 hours of tutoring

10b+(25 times 4) ≤ 130

= 10b+100 ≤ 130

10 times 3 = 30, which answers the question

Since 100 + 30 = 130

Therefore, the answer to the minimum amount of hours Robert has to tutor

to make a minimum of $130 is . . .

Answer:

Hopefully this makes sense, but x=+1 and y=-4

Step-by-step explanation:

Lets start with Y. how do you go from 7 to 3? you subtract 4. then, how do you go from 3 to -1? Well... lets subtract till we get to -1. That would be -4. Can you do that for the rest? if so, your answer is -4 for y. for x it just adds a number each time.

Answer:

-5/4

Step-by-step explanation:

The slop is rise over run

which means we need to find the rise over run of this equation:

So the question is how many times do you need to go up/down to get to the next plot on the graph? (Reminder up is positive while down is negative)

So, you go down 5 times which means the top of the slope is -5

Now, how many times do we need to run to get the next plot?

You need to run 4 times to the right to get the next point now we have all the things to solve the problem:

Slope=rise/run

Answer: -5/4

Hope this helps!

Answer:

The answer is undefined

Step-by-step explanation:

The slope of the line that passes through points (2, -3) and (2, 13) is not defined.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The line that passes through points (2, -3) and (2, 13)

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Plug the values to find the slope of the line:

m = (13 + 3)/(2-2) = 16/0 = not defined

Thus, the slope of the line that passes through points (2, -3) and (2, 13) is not defined.

Answer:

Yes, it's correct. Is that what you were asking for, or is there a part of the question that is missing?

Step-by-step explanation:

Answer:

x = -1  hope this is what you need :)

Step-by-step explanation:

[tex]-x^2+5x-6=2\\-x^2+5x-6-2=0\\-x^2+5x-8=0\\[/tex]

↝ Form into [tex]ax^2+bx+c = 0[/tex] where a > 0 (Optional)

[tex]x^2-5x+8=0[/tex] ↝ Multiply -1 for both sides.

↝ Then proceed with the Quadratic Formula.

x = [-b ± (√b²-4ac)]/2a ↝ Quadratic Formula

[tex]x=\frac{-(-5)+-\sqrt{(-5)^2-4(1)(8)}}{2(1)}\\x=\frac{5+-\sqrt{25-32}}{2}\\[/tex]

↝ As you can see that inside the square root, the numbers cannot be negative. Therefore, the solutions are imaginary.

↝ Solution with Real Numbers  System ↝  There are no real solutions.

↝ Solution with Complex Number System ↝

[tex]x=\frac{5+-\sqrt{25-32}}{2}\\x=\frac{5+-\sqrt{-7}}{2}\\x=\frac{5+-\sqrt{7}i }{2}[/tex]

Therefore, the answer for Complex Number System is (5±√7i)/2

Answer:

x = 7deg

Step-by-step explanation:

Answer:

  (3, 0)

Step-by-step explanation:

The line through these points intersects the x-axis at x=3.

The x-intercept is (3, 0).

_____

The x-intercept can be computed from ...

  x-intercept = x1 -y1(x2 -x1)/(y2 -y1)

  = -3 -(-4)(6-(-3))/(2-(-4)) = -3 +4(9/6) = -3 +6

  x-intercept = 3

Here, it is simple enough to plot the points and see where the line crosses the x-axis.

Answer:

There are 2 dogs

Explaination:

If there are 28 eyes in total,

Dogs- 4 eyes

Chickens- 8 eyes

Fishes - 16 eyes

In total they have 28 eyes

if there are 16 legs,

Dogs- 8 legs

Chickens- 8 legs

Fishes- 0 legs

So,

2 Dogs

4 Chickens

8 Fishes

( the problem even said that there are twice as many fish as chickens)

Answer:

-3(4c-2) -2c = -14c+6

Step-by-step explanation:

We need to find the equivalent expression for -3(4c-2) -2c.

First we open the brackets as follows :

-3(4c-2) -2c

= -12c+6-2c

=-12c-2c+6

=-14c+6

So, the equivalent expression is -14c+6.

Answer:

A. -1

Step-by-sep explanation:

If PQ is perpendicular to RS, therefore, the slope of RS would be the negative reciprocal of PQ.

Slope of PQ:

P(6,-2), Q(-2, 8)

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{8 -(-2)}{-2 - 6} = \frac{10}{-8} = -\frac{5}{4} [/tex]

Slope of RS:

Slope of RS is the reciprocal of the slope of PQ, since they are perpendicular.

⅘ is the reciprocal of -⁵/4. Therefore, the slope of RS = ⅘.

Use the slope formula to find the value of y in R(-4, 3), S(-9, y).

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Plug in the value

[tex] \frac{4}{5} = \frac{y - 3}{-9 -(-4)} [/tex]

[tex] \frac{4}{5} = \frac{y - 3}{-5} [/tex]

Cross multiply

[tex] (4)(-5) = (y - 3)(5) [/tex]

[tex] -20 = 5y - 15 [/tex]

Add 15 to both sides

[tex] -20 + 15 = 5y - 15 + 15 [/tex]

[tex] -5 = 5y [/tex]

Divide both sides by 5

[tex] \frac{-5}{5} = \frac{5y}{5} [/tex]

[tex] -1 = y [/tex]

y = -1
