Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (18, 0)

Point (10, -5)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute [SF]: $m=\frac{-5-0}{10-18}$
Subtract: $m=\frac{-5}{-8}$
Simplify: $m=\frac{5}{8}$

What is the limit of f (×) as x approaches - infinty

tatyana61 [14]

If the degree of numerator and denominator are equal, then limit will be leading coefficient of numerator divided by the leading coefficient of denominator.

So then the limit would be 3/1 = 3.

Alternatively,

$\displaystyle \lim_{x\to\infty}\dfrac{3x^2+6}{x^2-4}=\displaystyle \lim_{x\to\infty}\dfrac{3x^2+6}{x^2-4}\cdot\dfrac{1/x^2}{1/x^2}=\lim_{x\to\infty}\dfrac{3+\frac6{x^2}}{1-\frac4{x^2}} = \dfrac{3+0}{1-0}=\boxed{3}$

Hope this helps.

Answer:

See explanation

Step-by-step explanation:

From the graph,

After 1 hour passed, 2 inches of show fell
After 5 hours passed, 10 inches of snow fell
And so on

This means, that points (1,2), (5,10) lie on the graph. This graph passes through the origin, so its equation is

$y=kx,$

where k is the slope

Find k:

$2=k\cdot 1\\ \\k=2,$

so the equation is $y=2x$ and the slope is k = 2.

The slope means how many inches of snow fell in 1 hour.

In 1 hour, 2 inches of snow fell.
