Answer:

The correct answer is D.) y = -2x-3

Step-by-step explanation:

You can solve the given equation y - 5 = -2(x + 4):

y - 5 = -2(x + 4)         simplify the right side

y - 5 = -2x - 8            add 5 to both sides

y = -2x - 3

Answer:

D

Step-by-step explanation:

solve whats in (  ) first                               y-5= -2x -8

move the constant to the right                 y =  -2x - 8+5

(5 is the constant  )

add the sums                                              y= -2x -3

This is actually the slope intercept form

I need help solving this proportion!! <br><br> 3/x-1 = 2/x+4
Gelneren [198K]
1. Move 2/x to the left side of proportion by changing sign before it:
3/x - 1 - 2/x = 4

2. Move 1 to the right side of proportion and change it's sign as well:
3/x - 2/x = 4 + 1

3. Sum numerators in the left side of proportion since they have common denominator (x) abd also sum the numbers in the right side too:
(3-2)/x = 5

4. Calculate numerator in the left side of proportion:
1/x = 5

5. Move 1 to the right side of proportion by dividing that side by it:
x = 1/5

How many degrees is the angle below?
umka2103 [35]

Answer:

30 degrees

Step-by-step explanation:

the line (not at the 0) is what you measure from. Because the angle is visibly acute, we know that it must be less than 90 degrees, therefore the angle cannot be 150 degrees but 30 degrees (from the lower line)

A line passes through the point (8, -3) and has a slope of 3/4 write an equation in slope intercept form
erik [133]

Answer:

y = (3/4)x - 9

Step-by-step explanation:

The slope-intercept form of the equation of a straight line is y = mx + b.

Here we know x, y and m, but must find b.

Substituting 8 for x, -3 for y and 3/4 for m in the equation above results in:

-3 = (3/4)(8) + b, or (after multiplying all three terms by 4 to clear fractions):

-3 = 6 + b

Then b = -9, and the desired equation is     y = (3/4)x - 9

La media aritmética de los siguientes datos son respectivamente: 1, 4, 1, 1, 4, 2, 3, 1, 4, 2Respuesta necesaria. Opción única.
AlekseyPX

Answer:

<em>La media aritmética es 2.3</em>

Step-by-step explanation:

<u>Average o Promedio</u>

El promerio, average, o valor medio es un valor representativo de un conjunto de datos y se calcula según la fórmula:

\displaystyle \bar x=\frac{\sum x_i}{n}

Donde xi es el valor de cada dato, y n es el número de datos.

Los datos presentados son:

1, 4, 1, 1, 4, 2, 3, 1, 4, 2

Nótese que hay un total de n=10 datos. Aplicamos la fórmula recordando que el símbolo Σ significa <em>sumatoria</em>:

\displaystyle \bar x=\frac{1+ 4+ 1+ 1+ 4+ 2+ 3+ 1+ 4+ 2}{10}

\displaystyle \bar x=\frac{23}{10}=2.3

La media aritmética es 2.3
