Answer: v = 2

Step-by-step explanation:

30-48v+12 = -54

-48v = -54-30-12

\frac{-48v}{-48} = \frac{-96}{-48}

v = 2

Answer:

2

Step-by-step explanation:

6(5−8v)+12=−54

Divide through by 6, we have

5 — 8v + 2 = — 9

Collect like terms

— 8v = —9 — 2 — 5

—8v = — 16

Divide both side by the coefficient of v i.e —8

v = — 16/ —8

v = 2

Which of the following equations is the translation 2 units down of the graph of y = |x |?
Sveta_85 [38]
Y=|x|-2

this can be easily seen by testing f(0) for all functions:
f1(0)=|0-2|=2
f2(0)=|x+2|=2
f3(0)=|x|-2=-2
f4(0)=|x|+2=2

f(0)=|x|=0, because you want to translate it 2 units down -2 is the expected value

You are shopping for disposable camera, to hand out at a party. the daytime camera costs $2.75 and the flash camera costs $4.25.
Svetach [21]

The solutions that involve whole numbers of cameras are (7, 13), (8, 12), (9, 11), (10, 10), (11, 9), (12, 8) and (13, 7)

<h3>Write and solve a compound inequality for this solution.</h3>

The given parameters are:

  • Daytime cameras = $2.75
  • Flash camera = $4.25
  • Number of cameras = 20 cameras
  • Amount spent = Between $65 and $75

Represent the daytime camera with x and the flash camera with y.

So, we have:

x + y = 20

65 <=2.75x + 4.25y <= 75

Make y the subject in x + y = 20

y = 20 - x

Substitute y = 20 - x in 65 <=2.75x + 4.25y <= 75

65 <=2.75x + 4.25(20 - x) <= 75

Expand

65 <=2.75x + 85 - 4.25x <= 75

This gives

65 <=-1.5x+ 85  <= 75

Subtract 85 from the inequality

-20 <=-1.5x <= -10

Split the inequality

-1.5x >= -20 and -1.5x <= -10

Divide by -1.5

x <= 13.33 and x >= 6.67

Combine the inequality

6.67 <= x <= 13.33

<h3>List all of the solutions that involve whole numbers of cameras.</h3>

In (a), we have:

6.67 <= x <= 13.33

This means that:

x = 7, 8, 9, 10, 11, 12, 13

Recall that:

y = 20 - x

So, we have:

y = 13, 12, 11, 10, 9, 8, 7

So, the solutions that involve whole numbers of cameras are (7, 13), (8, 12), (9, 11), (10, 10), (11, 9), (12, 8) and (13, 7)

claudia has 8 yards of fabric she needs 3/4 of the fabric to make a banner how many yards of fabric does she need
daser333 [38]

Answer:

Step-by-step explanation:

Step 1 :

Given,

Length of fabric claudia has in yards = 8

Quantity of the fabric required by claudia to make the banner is 3/4 of the total quantity of fabric she has

Step 2 :

To get the required quantity of the fabric to make the banner, we need to multiply the total available quantity of the fabric by the required length of the fabric.

Hence we have the required length of fabric = 8 * 3/4 = 6 yards.

Find an equation for the line that passes through the points , −4−5 and , 2,5 .
Ronch [10]

Answer:

5x -3y = -5

Step-by-step explanation:

One formula that is useful for writing equations of lines through two points is ...

... (x2 -x1)(y -y1) = (y2 -y1)(x -x1)

Using the given points, this becomes ...

... (2 -(-4))(y -(-5)) = (5 -(-5))(x -(-4))

... 6(y +5) = 10(x +4) . . . . simpify

We can divide by 2 and subtract the left side to get ...

... 0 = 5x +20 -3y -15

... 0 = 5x -3y +5 . . . . . . . this is the <em>general form</em> equation of a line

Subtracting the constant gives the <em>standard form</em> equation.

... 5x -3y = -5

_____

<em>Comment on the solution</em>

As a rule, writing the equation this way from integer coefficients avoids fractions entirely. In the form with x on one side and y on the other, you can choose to move the x-term or leave it be, in order to ensure that it has a positive coefficient in the final equation. (Here we left it alone and moved the y-term.)

The standard form requires that the numbers in the equation be relatively prime (no common factors). That is why we divided by the common factor 2 in the development above.
