Identify the equation of a line in slope-intercept form that is perpendicular to y = -1/3 x + 2 and passes through (2, 1)

Airida [17]

Answer:

Step-by-step explanation:

The slope of a line perpendicular to another line is the opposite reciprocal of the slope of the other line, meaning if the slope of the other line is $-\frac{1}{3}$ , then the slope of the line perpendicular is $3$ .

Knowing this, we can start to construct the equation for the line:

$y = mx + b$

$y = 3x + b$

To solve for $b$ , we plug in the coordinates of the point that we know the line runs through, $(2, 1)$ :

$y = 3x + b$

$1 = 3(2) + b$

$1 = 6 + b$

$b = -5$

Therefore, the slope of the line that is perpendicular ot the line provided in the equation is the following:

$y = 3x - 5$

Two groups collected litter along the side of the road it takes each group 5 minuites to clean up a 200 yard section how long do

meriva

This is dividing
So 1 mile has 1760 yards so in total
2 miles = 3520 yards and it takes 5 minutes to clean up 200 yards (We divide)
3520 ÷ 200 = 17.6 ( Now we multiply)
17.6 x 5 = 88 minutes or ( 1 hour and 22 minutes)

Find the value of<br>a.) lim (x²-1)/(x²+1)<br>x−>∞<br>

Fed [463]

Answer:

$\displaystyle\lim_{x \to \infty} \frac{x^2-1}{x^2+1} \\ \text{take $x^2$ common from numerator and denominator} \\ \displaystyle\lim_{x \to \infty} \dfrac{1-\frac{1}{x^2}}{1+\frac{1}{x^2}} \\\text{Now put the limit}\\\displaystyle\lim_{x \to \infty} \frac{1-0}{1+0}= 1$
