\text {Hi! To solve this problem you must...}

\text {Do Keep Change Flip (KCF):}

\text {Keep: -3/8}

\text {Change: /  into *}

\text {Flip: 1/2 into 2/1}

\text {Your new problem should be -3/8*2/1}

\text {The Final Step is to Multiply:}

\text {Note: When Multiplying Fractions you multiply Numerator by Numerator}

\text {and Denominator by Denominator}

\text {-3/8*2/1=}

\fbox {-6/8}

\text {Best of Luck!}

\text {-LimitedX}

Write an equation (in slope-intercept form) of the line that passes through (0, 3) and (−5, 2.5).
Paladinen [302]

The equation of the line passing throught the points A(x_A,y_A) and B(x_B,y_B) has a form

\dfrac{x-x_A}{x_B-x_A}=\dfrac{y-y_A}{y_B-y_A}.

Now the equation of the line passing through points (0, 3) and (−5, 2.5) is

\dfrac{x-0}{-5-0}=\dfrac{y-3}{2.5-3}.

Simplify it:

\dfrac{x}{-5}=\dfrac{y-3}{-0.5},\\ \\0.5x=5(y-3),\\ \\5x=50y-150,\\ \\x=10y-30,\\ \\10y=x+30,\\ \\y=0.1x+3.

This equation is in slope-intercept form.

Answer: y=0.1x+3.

During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by
IrinaK [193]

Answer:

<em>The sound level would be at 80 decibels at 1 or 7 number of measures played</em>

Step-by-step explanation:

<u>Equations with Absolute Values</u>

We have the function s to represent the sound level in decibels:

s = 10|x - 4|+ 50

Where x is the number of measures of the music played.

We are required to find the value of x that makes s=80 decibels. We have to find the equation:

10|x - 4|+ 50 =80

Subtracting 50:

10|x - 4| =80-50

10|x - 4| =30

Dividing by 10:

|x - 4| =30/10=3

|x - 4| =3

For the absolute value be equal to 3, its argument could be positive or negative:

x-4=3

Or

x-4=-3

This leads us to two solutions:

x=3+4=7

x=7

Or

x-4=-3

x=4-3=1

x=1

The sound level would be at 80 decibels at 1 or 7 number of measures played

REY [17]

Answer:

1. 1

2. 5

3. lost 0.8 pounds

Step-by-step explanation:

The least value (or the most she lost) is in week 1

The greatest value (or the most she gained) is in week 5

When you add all the values together, you get:

-4.1 (lost)

3.3 (gained)

3.3 - 4.1 = -0.8

She lost a total of 0.8 pounds

These are your answers

Hope this helps!
