3|x+5|=7 Please answer as soon as possible

Answer:

The | signs are absolute value signs. Absolute value just makes a negative value turn positive, because technically there is no negative value. For example |-x+5| turns into x+5. If it's already positive, it stays the same. So basically, they're just acting as parenthesis right now. Just distribute the 3 and get 3x+15=7. subtract 17 and get 3x=-8. Divide both sides by three, and you should get x= -8/3. But wait, there's more. Since this is an absolute value equation, there should be more than one answer. Simply make the number on the other side negative. 3x+15=-7. subtract 15 and get -22. Keep going and your answer should be -22/3.

So in conclusion, your two answers are -8/3 and -22/3.

So right now i'm doing "solving Inequalities" i need help with this question<br> 3v-12&gt;5v+10
LenKa [72]

Answer:

v < -11

Step-by-step explanation:

  1. Combine like terms: 3v - 5v > 12 + 10
  2. Simplify: -2v > 22
  3. Divide each side by -2 to cancel out the -2 next to v. It should now look like this: v < -11

I hope this helps!

188 to 42 what is the percent change
Mekhanik [1.2K]

Answer:

Step-by-step explanation:

so we are gonna have a percent decrease because it went from 188 to 42

decrease = (original number - new number) / (original number ) * 100

                = (188 - 42) / (188) * 100

                = (146 / 188) * 100

                = 0.7766 * 100

                = 77.66% decrease....not sure if u need ur answer rounded to the nearest percent or not....if so, its a 78% decrease

Choose the equation for the relationship shown in the graph.
uysha [10]

Answer:

B) y = x - 50

Step-by-step explanation:

It is B because the graph's y-intercept lies on the point (0, -50), hence the equation, y = x <u>- 50</u>. In addition, you can verify that B is the correct answer because the slope of the graph is positive, and so the x-value also must be positive.

Compute the greatest root of x^4-x^3-19x^2+4x+60=0. Express your answer in simplified radical form.
erik [133]

Answer:

your answer can be either

Step-by-step explanation:

x = 5

x = 3

 x=  0.0000 - 2.0000 i  

 x=  0.0000 + 2.0000 i  

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 ((((x4)-(8•(x3)))+19x2)-32x)+60  = 0  

Step  2  :

Equation at the end of step  2  :

 ((((x4) -  23x3) +  19x2) -  32x) +  60  = 0  

Step  3  :

Polynomial Roots Calculator :

3.1    Find roots (zeroes) of :       F(x) = x4-8x3+19x2-32x+60

Polynomial Roots Calculator is a set of methods aimed at finding values of  x  for which   F(x)=0  

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  x  which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  1  and the Trailing Constant is  60.  

The factor(s) are:  

of the Leading Coefficient :  1

of the Trailing Constant :  1 ,2 ,3 ,4 ,5 ,6 ,10 ,12 ,15 ,20 , etc
