The equation of line "m" is 5x-3y=2<br>what is the slope of a line that is perpendicular to line M?

sdas [7]

The slope of this line is 5/3 so a perpendicular slope would be opposite reciprocal to this or -3/5

Write an equation of the line that passes through the given point and has the given slope. (1,-5); slope: - 2/3 SLOPE INTERCEPT

Elenna [48]

Answer:

y = $-\frac{2}{3}$ x - $-\frac{13}{3}$

Step-by-step explanation:

Given dimensions:

Slope = $-\frac{2}{3}$

Coordinates = (1, -5)

Now;

Equation of the line through the given points;

Solution:

The equation of a line is given as;

y = mx + c

x and y are the coordinates

m is the slope

c is the intercept

So;

let us find the y-intercept;

-5 = $-\frac{2}{3}$ x 1 + C

c = -5 + $\frac{2}{3}$ = $-\frac{13}{3}$

The equation of the line is ;

y = $-\frac{2}{3}$ x - $-\frac{13}{3}$

Drag each tile to the correct box. Arrange the angles in increasing order of their cosines.

inna [77]

Answer:

$\frac{3\pi}{4}$

Step-by-step explanation:

we are given different angles

we can see that each angles have different denominators

so, firstly we will find common denominators

denominators are 1 , 2,3,4,6

so, LCD will be 12

now, we will make denominator of all terms 12

$\frac{3\pi}{4} =\frac{3\pi\times 3}{4\times 3}=\frac{9\pi}{12}$

$\pi =\frac{\pi\times 12}{1\times 12}=\frac{12\pi}{12}$

$\frac{7\pi}{6} =\frac{7\pi\times 2}{6\times 2}=\frac{14\pi}{12}$

$\frac{5\pi}{3} =\frac{5\pi\times 4}{3\times 4}=\frac{20\pi}{12}$

$\frac{7\pi}{4} =\frac{7\pi\times 3}{4\times 3}=\frac{21\pi}{12}$

$\frac{4\pi}{3} =\frac{4\pi\times 4}{3\times 4}=\frac{16\pi}{12}$

$\frac{3\pi}{2} =\frac{3\pi\times 6}{2\times 6}=\frac{18\pi}{12}$

$2\pi =\frac{2\pi\times 12}{1\times 12}=\frac{24\pi}{12}$

we can see that denominators are same

so, we can arrange it according to numerators as

$\frac{9\pi}{12}$

we can replace values

and we get order as

$\frac{3\pi}{4}$
