|2x - 1|  =  | - x - 2|

Thus ;

2x - 1 =  - x - 2

Add both sides x

2x + x - 1 =  - x + x - 2

3x - 1 =  - 2

Add both sides 1

3x - 1 + 1 =  - 2 + 1

3x =   - 1

Divide both sides by 3

\frac{3x}{3}  =  \frac{ - 1}{3}  \\

x =  -  \frac{1}{3}  \\

<h2>Or </h2>

2x - 1 =  - ( - x - 2)

2x - 1 = x + 2

Subtract both sides x

2x  - x  - 1 = x - x + 2

x - 1 = 2

Add both sides 1

x - 1 + 1 = 2 + 1

x = 3

There u go ...

Quinn leaves her house at 10:00 am and runs 3 miles at a steady pace of 6 miles per
bogdanovich [222]

Using the relation between velocity, distance and time, it is found that Quinn returns home at 1 pm.

Velocity is <u>distance divided by time</u>, that is:

v = \frac{d}{t}

  • She walked <u>3 miles</u> at a velocity of <u>6 miles per hour</u>, thus d = 3, v = 6. The time is:

v = \frac{d}{t}

t = \frac{d}{v} = \frac{3}{6} = 0.5

  • Thus, she arrived at 10:30 am, and took a lunch break of 1 hour, so she started to return at 11:30 am.
  • Distance of <u>3 miles,</u> velocity of <u>2 miles per hour,</u> thus d = 3, v = 2. The time she took to return, in hours, is:

t = \frac{d}{v} = \frac{3}{2} = 1.5

1.5 hours after 11:30 am is 1 pm, thus, Quinn returns home at 1 pm.

write the expressions for when you translate the graph of y = |x+2| a) one unit up b) one unit down c) one unit to the left d) o
irina1246 [14]

Hello!

This question is about which values you are changing when you are transforming an equation.

Let's go through the parent function for an absolute value equation and its various transformations.

y=a|b(x-c)|+d

Since we are only looking at horizontal and vertical transformations, we only need to worry about the c and d values.

The c value of a function determines a function's horizontal position, and the d value of a function determines a function's vertical position.

One thing to note here is that the c value is being subtracted from the x value, meaning that if the function is being transformed to the right, you would actually be subtracting that value, while the d value behaves like a normal value, if it is being added, the function is transformed up, and vice versa.

Now that we know this, let's write each expression.

a) y=|x+2|+1

b) y=|x+2|-1

c) y=|x+3|

d) y=|x+1|

Hope this helps!
