Answer:

9-7x+9+25+6x-4=47-x

Step-by-step explanation:

5÷x-4 - 2÷x+2 = 4÷x-4
Alborosie
I'd suggest you begin by subtracting 4 / (x-4) from both sides.  Doing that would leave you with    1 / (x-4)   -     2 / (x+2) =  0.

LCD is (x-4)(x+2).  Mult. all three terms by (x-4)(x+2).  The resulting equation is 

x+2 - 2(x-4) = 0.     Then x+2 = 2x - 8  =>  x = 10

Subst. 10 for x in the original equation to verify that 10 is indeed a solution.

Stephon makes the following statements: statement 1 lim x -3 f(x) exists and is equal to 1 statement 2 lim x 1 f(x) exists and i
Mandarinka [93]

Neither statement 1, nor statement 2 are correct

The given Stephon's statements are;

Statement 1; \mathbf{\lim \limits  _{x \to -3} f(x)}  \ \mathbf{Exist} \ and \mathbf{\lim \limits  _{x \to -3} f(x) = 1}

Statement 2; \mathbf{\lim \limits  _{x \to 1} f(x)}  \ \mathbf{Exist} \ and \mathbf{\lim \limits  _{x \to 1} f(x) = 1}

The analysis of the graph and reason for the answer

From the graphed line on the left of the y-axis, we have an open circle at x = -3, and an arrow at the other end pointing towards negative infinity, (-∞) which indicates that the domain is -∞ ≤ x < -3, therefore, at x = -3, f(x) does not exist, therefore, we can write the following statement

The limits of the domain and range of the graph includes;

\mathbf{\lim \limits  _{x \to -3} f(x)} = \mathbf{Does \ not \ exist}

f(x) = Defined for -∞ ≤ x < -3

Similarly, from the graphed line on the right of the y-axis, we have an open circle at x = 1 and an arrow at the other end of the line f(x) = 4 pointing towards positive (+∞) infinity, which indicates the domain and the graph of the function is 1 < x ≤ ∞ , therefore, f(x) does not exist at x = 1, and we can write

\mathbf{\lim \limits  _{x \to 1} f(x)} = \mathbf{Does \ not \ exist}

From we above, we have that neither statement 1, nor statement 2 are correct

What is the slope of Y= -3x + 2
notka56 [123]

Answer:

m = -3

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

<em>m</em> = slope

<em>b</em> = y-intercept

We are given the equation y = -3x + 2. Therefore, our slope is -3 and our y-int is 2.
