How can help me with this operation about Pre-Calculus. Simplify

Mrrafil [7]

If we want to compute $f(2+h)$ , we have to substitute every occurrence of $x$ with $2+h$ in the definition of the function:

$f(x)=x^2-11x \implies f(2+h) = (2+h)^2-11(2+h) = 4+4h+h^2-22-11h = h^2-7h-18$

Similarly, computing $f(2)$ means to substitute the input with 2:

$f(x)=x^2-11x \implies f(2) = 2^2-11\cdot 2 = 4-22 = -18$

So, we have

$f(2+h) - f(2) = h^2-7h-18 - (-18) = h^2-7h$

And finally

$\dfrac{f(2+h)-f(2)}{h} = \dfrac{h^2-7h}{h} = h-7$

The three sides of a triangular lot are represented by x, 2x, and 3x + 2. Find each side if the perimeter of the triangular lot

Svetlanka [38]

To find the perimeter, you would add all the sides. Because we know the perimeter, we can represent this as an equation that needs solved.

362 = x + (2x) + (3x + 2), combine the like terms
362 = 6x + 2, subtract 2 from both sides
-2 -2
360 = 6x, divide both sides by 6
6 6

x = 60 feet

side 1 = 60 feet
side 2 = 120 feet
side 3 = 182 feet

check your work: 60 + 120 + 182 = 362 feet

Answer:

Answer: Quadrant 4

Step-by-step explanation:

Graph of Functions

Let's analyze the function

$\displaystyle y=\frac{x^2+3x}{x+1}$

To better understand the following analysis, we'll factor y

$\displaystyle y=\frac{x(x+3)}{x+1}$

For y to have points in the first quadrant, at least one positive value of x must produce one positive value of y. It's evident that any x greater than 0 will do. For example, x=1 will make y to be positive in the numerator and in the denominator, so it's positive

For y to have points in the second quadrant, at least one negative value of x must produce one positive value of y. We need two of the factors that are negative. It can be seen that x=-2 will make y as positive, going through the second quadrant.

For the third quadrant, we have to find at least one value of x who produces a negative value of y. We only need to pick a value of x that makes one or all the factors be negative. For example, x=-4 produces a negative value of y, so it goes through the third quadrant

Finally, the fourth quadrant is never reached by any branch because no positive value of x can produce a negative value of y.
