Answer:

m=-7/2

Step-by-step explanation:

 (5 • (m + 2) -  m) -  (2m + 3)  = 0

 2m + 7  = 0

3.1      Solve  :    2m+7 = 0

Subtract  7  from both sides of the equation :

                     2m = -7

Divide both sides of the equation by 2:

                    m = -7/2 = -3.500

Answer

5(m+2)-m=2m+3

5m+10-m=2m+3

5m-2m-m=-10+3

3m-m=-10+3

2m=-7

m= -7/2

m= -3.5

A magazine subscription costs $29.88 for 12 issues or $15.24 for 6 issues. Which subscription costs more per issue? How much mor
Valentin [98]

Answer:

The magazine that cost $15.24 for 6 issues cost more by $0.60/60 cents.

Step-by-step explanation:

Since $15.24 is 6 issues each and you need to even out the issues add $15.24+$15.24 then you would get $30.48, because its 15.24 each 6 add them both and it would be 12 issues. And the first issue $29.88 for 12 issues is  only $29.88 while the other is $30.48 so the one with 6 issues/the second cost more than the first.

60 cents more because 29.88+60=30.48.

Can someone help me with this
Daniel [21]

Considering the given graph of the function, we have that:

  • Function Notation: f(1) = -3.
  • Ordered pair: (1,-3).
  • Verbal statement: If x is equal to -1, then the value of f(x) is equal to -3.
<h3 /><h3>How to find the numeric value of a function looking at it's graph?</h3>

To find the numeric value of the function, we get a value of x(horizontal axis), and then look at the corresponding value y(vertical axis), then y = f(x).

In the graph of this function, we have that when x = 1, y = -3, hence:

  • Function Notation: f(1) = -3.
  • Ordered pair: (1,-3).
  • Verbal statement: If x is equal to -1, then the value of f(x) is equal to -3.

What is 3x^4 + 5x^3 + x^2 - 5 divided by x + 2
Brilliant_brown [7]
Remember, there is a missing term which is crucial to solving this, and that is 0x.

Ima use synthetic division, because that's the quicker option here:

The zero of x+2 is -2...

-2 | 3 5 1 0 -5
-6 2 -6 12
_____________
3 -1 3 -6 7

(Sorry, I'm unsure how to fix the formatting, plus I'm new to this. The -6 and such on the second line should be below the 5 and following of the first line, and the 3 and such on the last line should be below the 3 and following on the first line, leaving a space between the 3 on the first and third line.)

So the answer is: A. 3x^3 - x^2 + 3x - 6 + 7/(x+2)
