5.25

Step-by-step explanation:

hint: anytime you see a - before (  and its not like (for example) -2 then you put a 1 like this -1(

2-1(4x+8)= -12

2-4x+7= -12

(combine like terms [2 and 7 in this case] )

9-4x= -12

(subtract 9)

-4x = -21

(divide by -4)

x=5.25

Step-by-step explanation:

Answer:

The answer is

[tex] \huge y = - \frac{1}{4} x - 6[/tex]

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

where

m is the slope

( x1 , y1) is the point

From the question the point is ( 8 , - 8) and slope -1/4

We have

[tex]y + 8 = - \frac{1}{4} (x - 8) \\ y + 8 = - \frac{1}{4} x + 2 \\ y = - \frac{1}{4} x + 2 - 8[/tex]

We have the final answer as

[tex]y = - \frac{1}{4} x - 6 \\ [/tex]

Answer:

Thus: a7=-1

Step-by-step explanation:

Arithmetic Sequences

The arithmetic sequences are identified because each term is obtained by adding or subtracting a fixed number to the previous term.

The equation to calculate the nth term of an arithmetic sequence is:

[tex]a_n=a_1+(n-1)r[/tex]

We know: a12=29, a16=53, thus

[tex]a_1+(12-1)r=29[/tex]

[tex]a_1+(16-1)r=53[/tex]

Simplifying:

[tex]a_1+11r=29[/tex]

[tex]a_1+15r=53[/tex]

Subtracting both equations:

[tex]4r=53-29=24[/tex]

Solving:

[tex]r=24/4[/tex]

r=6

The 7th term can be found as 5 terms before the 12nd:

[tex]a_7=a_{12}-5r[/tex]

[tex]a_7=29-5*6=29-30=-1[/tex]

Thus: a7=-1

Answer:

56.55

Step-by-step explanation:

Answer:

15

Step-by-step explanation:

If Maggies age is, for example, x, we can say that her brothers age is 4x-6. We know from the problem that Maggies age (x) plus her bothers age, (4x-6) is 69. So,

4x-6+x=69

5x-6=69

5x=75

x=15

So, Maggie is 15.

Answer: Maggie is 15 years old

Step-by-step explanation:

69 = (4m - 6) + m     --- get an equation

69 - m = 4m - 6        --- lets subtract  m from both sides first

75 - m = 4m              --- add 6 on both sides

75 = 5m                    --- add m on both sides

15 = m                       --- divide by 5 on both sides

m = 15, so Maggie is 15 years old

Let's check:

69 = (4(15)-6) +15

69 = (60 - 6) + 15

69 = 54 + 15

69 = 69

X+y=-5

-x -x

y=-x-5 is the ending equation.

How to graph:

The y-intercept, or point where the graph starts, is -5

From there go down 1, right 1.

M=-x

B=-5

Answer:  m = -1   b = -5

Step-by-step explanation:

Rewrite the equation in "slope-intercept form"   y = mx +b .

m is the slope  

b is the y-intercept, where the graph of the line crosses the y-axis

To rewrite the equation, to get "y" alone on the left side, subtract x from both sides:

x + y = -5

-x + x + y = -x - 5  (left side -x +x =0 so "cancel")

y = -x -5

You get  the slope "m" from the coefficient of x, (invisible 1, sometimes)

since there is a negative sign, the coefficient is -1   That is m, the slope.

A negative slope goes down from left to right.

For  -1, down one over 1 square.

Your graph should look like the screenshot below.

I hope this helps you understand better!

Given parameters:

Dimension of the room  = 6 inches by 11 inches;

Unknown:

Area of the actual room = ?

Solution:

The area of the room = length x breadth

Now, we need to convert inches to feet;

                Scale;

                       1 inch = 1 foot

                        6 inches  = 6 foot

                       1 inch = 1 foot

                       11 inch = 11 foot

The area of the room = 6 x 11 = 66 square feet

Answer:

6 x 11 = 66 square feet

Step-by-step explanation:

Hey there!

The point shows the coordinates of (-2,1) and (4,6).

Now, When two points are given on a st.line, we use double point formula.

So, use formula;

[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]

Put all values of x and y coordinates.

[tex](y - 1) = \frac{6 - 1}{4 + 2} (x + 2)[/tex]

Simplify it.

[tex](y - 1) = \frac{5}{6} (x + 2)[/tex]

[tex]y = \frac{5}{6} x + 2 \times \frac{5}{6} + 1[/tex]

[tex]y = \frac{5}{6} x + \frac{ 8}{3} [/tex]

Therefore, the equation of a line is y= 5/6x+8/3.

There are 2950 songs would you have to listen in a row before you heard a song by your favorite artist.

What is random shuffle of songs?

Shuffle play is a type of music playback in which all tracks are selected at once and songs are played in a random order. Media player software, digital audio players, and CD players all frequently have it.

Given: You have 3,000 songs downloaded to your mobile phone.

Of these songs, 50 songs are by your favorite artist.

So, the number of songs would you have to listen in a row before you heard a song by your favorite artist are,
