Commutaitve has to do with moving around the order

it is a+b=b+a

so x+5=5+x, therefor

9(x+5)=9(5+x)

Find the equation for the line that passes through the point (−2,0), and that is perpendicular to the line with the equation 2/3
patriot [66]

Answer:

y = 3/2 x + 3

Step-by-step explanation:

2/3 x + y = -14/3

y = -2/3 x − 14/3

The slope of this line is -2/3.  So the perpendicular slope is the opposite of the inverse:

m = -1 / (-2/3)

m = 3/2

We know the slope of the line and a point on the line, so using point-slope form:

y − 0 = 3/2 (x − (-2))

Simplifying into slope-intercept form:

y = 3/2 (x + 2)

y = 3/2 x + 3

HELP!!! Find the exact value of <br> cos A in simplest radical form.
Galina-37 [17]

Answer:

cos A = 9/41

Step-by-step explanation:

cosine is a function that puts together the ADJACENT side of a triangle in a ratio with the HYPOTENUSE.

So from angle A the side length 9 is right next to A so it is the ADJACENT side. The HYPOTENUSE is the longest side ,that is the side length 41.

so cos A = ADJ/HYP

cos A = 9/41

It could be that the directions were confusing bc they said simplest radical form. Many, but not all right triangles have one or more sidesides that have a radical as part of their measure. This triangle doesn't. If you get a radical in the denominator of a ratio, be sure to rationalize so that there is no radical on the bottom.
