Answer: improper fraction : x= 29/4

Mixed number: x=  7   1/4

Decimal form: x=  7.25

Step-by-step explanation: <em>* x is the shortened of saying 1x *</em>

  1. Add like terms (out of the equation combine +3x and +1x which is<u><em> 4x</em></u>. And combine +2and  -6 which is <u><em> -4 </em></u>) and now the equation is reads                   4x -4= 25
  2. Move the "-4" to the other side pf the equation by Addition Property of Equality  4x -4 = 25                                                                                              .                   +4    +4                                                                                                    .                 4x    = 29
  3. Then, separate the 4 from the x to get it by itself by Dividing 4 into 4x . *Remember what you do to one side of the equation do to other side*       4x/4 = 29/4                                        
  4. The answer now depends what the teacher wants if she want it to stay as an improper fraction it will be 29/4 if it wanted in Mixed number its   7 and 1/4 and if its necessary to have in decimal form its 7.25.

Answer:

x= 7.25

Step-by-step explanation:

3x+2+x-6=25

Step 1- Add the variables

4x+2-6=25

Step 2- Add to both sides

4x+2-6= 25

       +6   +6

Step 3- Subtract to both sides

4x+2= 31

   -2     -2

Step 4- Divide to both sides

<u>4x</u>=<u>29</u>

4    4

x=7.25

Here are the graphs of L(x) and R(x) what are the values of L(2) and R(2)
Sedaia [141]

Using the function graph given, it is found that:

  • L(2) = 7.
  • R(2) = 1.

When a piece-wise function is given, that is, a function that has <em>multiple definitions</em>, the numeric value at x when the definition changes is given by the closed circle.

  • For function L(x), when x = 2, the closed circle is at y = 7, hence, L(2) = 7.
  • For function R(x), when x = 2, the closed circle is at y = 1, hence, R(2) = 1.

Need help on this one thanks

Answer:

Y = 10/7X + 4

Y intercept = 4

Slope = 10/7

X intercept = -40/7

Step-by-step explanation:

Incase you are asked the equation of the line

The slope intercept equation is as follows -

(1)....Y = mx + b

where m - Slope

b - Y - intercept

the standard formula of slope which is commonly referred to as "the rate of change" is -

(2) .....m= Y2 - Y1 / X2 - X1

in this case you can refer to the final and initial X and Y values directly from the small points on the line.

and so(3)..... - X1 = -6 X2 = 6

- Y2 = 9 Y1 = -1

the y intercept is defined as the value we get whenever X id zero. and X has a value of zero when a line crosses the y axis.

thus, X = 0 & Y = 4 ( 0 , 4 )

now lets substitute our values(3) into the slope formula (equation 2)

m = 9 - - 1 / 6 - - 1 = 10/7

now that we found the line's slope, let's simply plug the y intercept

into the slope intercept formula (1)

Y = 10/7X + 4
