What is the difference x/x^2-16-3/x-4

kenny6666 [7]

General Idea:

When simplifying a rational expression, we need to do the below steps:

(i) Factor the Denominator of each fraction

(ii) Identify the Least Common Denominator (It is the product of prime factors involved with its highest exponent)

(iii) Identify and rewrite the equivalent fraction with the desired LCD.

(iv) Once the denominator are same, Combine the numerator.

Applying the concept:

What is the difference x/x^2-16-3/x-4

I assume that you mean to type the expression $\frac{x}{x^{2}-16} -\frac{3}{x-4}$

Step 1: Factoring $x^{2} -16$

$x^{2} -16=x^{2} -4^{2} =(x+4)(x-4)$

Step 2: Identifying the LCD, we get $(x+4)(x-4)$

Step 3: Rewriting the second fraction by multiplying x+4 on both top and bottom of second fraction so that we get the LCD.

$\frac{x}{x^2-16}-\frac{3}{x-4}=\frac{x}{(x+4)(x-4)} -\frac{3*(x+4)}{(x-4)*(x+4)} Step 4: Combine like terms since the denominators are same[tex] \frac{x-3(x+4)}{(x+4)(x-4)} =\frac{x-3x-12}{(x+4)(x-4)}=\frac{-2x-12}{(x+4)(x-4)} =\frac{-2(x+6)}{(x+4)(x-4)}$

Conclusion:

In factored form the simplified expression $=\frac{-2(x+6)}{(x+4)(x-4)}$

In expanded form the simplified expression $=\frac{-2x-12}{x^2-16}$

The pie graph shows Katie and David's household budget. The 25% mark represents utilities. If Katie and David spend $400 a month

Vesnalui [34]

Answer is B. $1,600

Given:
part = $400
percentage of the part = 25%
whole = ?

To get the whole or total monthly budget, simply divide the part by its corresponding percentage.

$400 / 0.25 = $1600

Other formulas to consider if other facts are given:

% of Part to the Whole = Part/Whole * 100%
= 400/1600 * 100%
= 0.25 * 100%
= 25%

Value of the part of a whole = Whole * % of part
= 1600 * 25%/100%
= 400

Find a vector function, r(t), that represents the curve of intersection of the two surfaces. the paraboloid z = 7x2 + y2 and the

Akimi4 [234]

Letting $x=t$ , we get $y=3x^2=3t^2$ and $z=7x^2+y^2=7t^2+(3t^2)^2=7t^2+9t^4$ , so we can parameterize the intersection by

$\mathbf r(t)=\langle t,3t^2,7t^2+9t^4\rangle$

where $-\infty$ .
