Step-by-step explanation:
Rearrange this Absolute Value Inequality
Absolute value inequalitiy entered
|-4x+1| > 3
Clear the Absolute Value Bars
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |-4x+1|
For the Negative case we'll use -(-4x+1)
Solve the Negative Case
-(-4x+1) > 3
Multiply
4x-1 > 3
Rearrange and Add up
4x > 4
Divide both sides by 4
x > 1 for the negative
For the Positive case we'll use (-4x+1)
(-4x+1) > 3
Rearrange and Add up
-4x > 2
Divide both sides by 4
-x > (1/2)
Multiply both sides by (-1)
Remember to flip the inequality sign
x < -(1/2)
Which is the solution for the Positive Case

Explanation:
Rearrange this Absolute Value Equation
Absolute value equalitiy entered
|x-2| = 4x+4
STEP

:
Clear the Absolute Value Bars
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |x-2|
For the Negative case we'll use -(x-2)
For the Positive case we'll use (x-2)
STEP
3
:
Solve the Negative Case
-(x-2) = 4x+4
Multiply
-x+2 = 4x+4
Rearrange and Add up
-5x = 2
Divide both sides by 5
-x = (2/5)
Multiply both sides by (-1)
x = -(2/5)
Which is the solution for the Negative Case
(x-2) = 4x+4
Rearrange and Add up
-3x = 6
Divide both sides by 3
-x = 2
Multiply both sides by (-1)
x = -2
Which is the solution for the Positive Case

Stephen calculated the linear regression equation to be y = -7.8x + 246.3. Using this equation, find the cost of a
room 5 city blocks away from Time Square.
1) $195
2) $207
3) $238
4) $285
What’s the answer?
Answer:
$207
Step-by-step explanation:
Given the following :
Data:
X : Distance From Times Square (city blocks)
Y: Cost of a Room (dollars) (y)
The linear regression model generated for the data :
y = -7.8x + 246.3
y = predicted variable ; - 7. 8 = slope of model ; x = predictor variable ; 246.3 = intercept
Using the model:
The cost of a Room 5 block away :
x = 5
y = -7.8(5) + 246.3
y = - 39 + 246.3
y = $207.3
complete the table for values for y=x^2-x-2
Answer:
x -3 -2 -1 0 1 2 3
y 10 4 0 -2 -2
Step-by-step explanation:
The given equation is y=x²-x-2.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
We need to find the y values of the give x values.
Given that, x = -3 -2 -1 0 1 2 3
When x = -3, y = (-3)²-(-3)-2
= 9+3-2 = 10
When x = -2, y = (-2)²-(-2)-2
= 4+2-2
= 4
When x = -1, y = (-1)²-(-1)-2
= 1+1-2
= 0
When x = 0, y = 0²-0-2
= -2
When x = 1, y = 1²-1-2
= -2
When x = 2, y = 2²-2-2
= 0
When x = 3, y = 3²-3-2
= 4
So, the complete table is
х -3 -2 -1 0 1 2 3
y 10 4 0 -2 -2 0 4
There, the y values of the given x values in the given equation is y = 10, 4, 0, -2, -2, 0, 4.

Lin read for X minutes and Elena read for 5/8 more than that. Write an expression for the number of minutes elna read.only use decimals in your expression
Elena read X + 0.625 minutes.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
Given:
Lin read for X minutes and Elena read for 5/8 more than that.
That means,
the number of minutes Elena read,
= number of minutes Lin read + 5/8
= X + 5/8
= X + 0.625
Therefore, X + 0.625 is the required expression.

During the summer, Jody earns $10 per hour babysitting and $15 per hour doing yardwork. This week she worked 34 hours and earned $410. If x represents the number hours she babysat and y represents the number of hours she did yardwork, which system of equations models this situation?
Given:
Jody earns $10 per hour babysitting and $15 per hour doing yardwork.
This week she worked 34 hours and earned $410.
To find:
The system of equations models this situation.
Solution:
Let x represents the number hours she babysat and y represents the number of hours she did yardwork.
Total number of hours is 34.
[tex]x+y=34[/tex]
Total income is $410.
[tex]10x+15y=410[/tex]
Therefore, the required system of equations has equations [tex]x+y=34[/tex] and [tex]10x+15y=410[/tex].

The frequency vibrations for a certain guitar string When is blood can be determined by the equation below, Where F is the number of vibration per second and T is measured in pounds.If the frequency of the vibrations is 600 vibrations per second, How many pounds of tantrums was used to plug the string? F = 200sqrt(T)
Answer:
9 poundsStep-by-step explanation:
Given the frequency vibrations for a certain guitar string modeled by the equation
F = 200√T where:
T is amount of tantrums in pounds
If the frequency of the vibrations is 600 vibrations per second, the amount of pounds in tantrums will be gotten by substituting F = 600 into the equation and calculating T as shown:
600 = 200√T
Divide both sides by 200
600/200 = 200√T /200
3 = √T
Square both sides
3² = (√T)²
9 = T
T = 9
Hence 9 pounds of tantrum was used to plug the string

Answer:
[tex]\boxed {x = -2}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]9 - 4x = 17[/tex]
-Subtract both sides by [tex]9[/tex]:
[tex]9 - 9 - 4x = 17 - 9[/tex]
[tex]-4x = 8[/tex]
-Divide both sides by [tex]4[/tex]:
[tex]\frac{-4x}{-4} = \frac{8}{-4}[/tex]
[tex]\boxed {x = -2}[/tex]
Therefore, value of [tex]x[/tex] is [tex]-2[/tex].
