Through: (2,5), perp. to y =- 2/3x +3
chubhunter [2.5K]

Find the equation of line passes through point (2, 5) and perpendicular to line having equation y =- 2/3x +3

<h3><u>Answer:</u></h3>

The equation of line passes through point (2, 5) and perpendicular to line having equation y =- 2/3x +3 in slope intercept form is y = \frac{3}{2}x + 2

<h3><u>Solution:</u></h3>

Given that line passes through (2, 5) and perpendicular to line having equation y = \frac{-2}{3}x + 3

Let us first find slope of original line

<em><u>The slope intercept form of line is given as:</u></em>

y = mx + c ------ eqn 1

Where "m" is the slope of line and "c" is the y - intercept

On comparing the slope intercept form y = mx + c and given equation of line y = \frac{-2}{3}x + 3 we get

m = \frac{-2}{3}

Thus slope of given line is m = \frac{-2}{3}

We know that product of slopes of given line and slope of line perpendicular to given line is always -1

Slope of given line x slope of line perpendicular to it = -1

\begin{array}{l}{\frac{-2}{3} \times \text { slope of line perpendicular to it }=-1} \\\\ {\text { slope of line perpendicular to it }=\frac{3}{2}}\end{array}

Let us find equation of line with slope m = \frac{3}{2} and passes through (2, 5)

Substitute m = \frac{3}{2} and (x, y) = (2, 5)

5 = \frac{3}{2} \times 2 + c\\\\5 = 3 + c\\\\c = 2

<em><u>Thus the required equation of line is:</u></em>

Substitute m = \frac{3}{2} and c = 2 in eqn 1

y = \frac{3}{2}x + 2

Thus the equation of line perpendicular to given line is found out

Some isosceles triangles are not equilateral. a true or b false
Bas_tet [7]
That's true.  The definition of an isosceles triangle is that it has at least 2 sides equal in length.  Therefore, isosceles can be equilateral, but equilateral cannot be isosceles.

HELP I NEED HELP ASAP
notsponge [240]

Answer:

3w² + 10w +8 (C)

Step-by-step explanation:

A rectangle has a length that is 3 times its width, w, in inches. The width is increased by 2 inches, and the length is increased by 4 inches. Which expression represents the area of the larger rectangle?

First, remember that the length of the first rectangle is 3 * w, or 3w.

Now, onto the second rectangle.

The width is increased by 2, so it becomes w + 2

The length is increased by 4, so it becomes 3w +4.

Area is length times width, so the area is

(w + 2)(3w + 4)

Simplify.

3w*w + 4*w + 2*3w + 2*4 =

3w² + 4w + 6w +8

3w² + 10w + 8, or C

Sara can finish 5 laps around the track in 6 minutes. What is her average speed in miles per hour, if it takes 12 laps around th
sveticcg [70]

9514 1404 393

Answer:

  4 1/6 miles per hour

Step-by-step explanation:

6 minutes is 1/10 hour, so Sara's speed is ...

  speed = distance/time

  speed = (5/12 mi)/(1/10 h) = 50/12 mi/h

  speed = 4 1/6 mi/h

Sara's speed is 4 1/6 miles per hour.

Is graph a proportional
klemol [59]
Yes, Graphs (depending on which one but I'm assuming your talking about coordinate grids) are proportional because they have on vertical and one horizontal line dividing them. They extend infinitely
