Which equation represents the line that is perpendicular yo y=3/2x+1 and passes through (-12,6)
klemol [59]

Answer:

y = -2/3x - 2

Step-by-step explanation:

Step 1: Find slope <em>m</em> of perpendicular line

<em>Simply take the negative reciprocal of the given line</em>

m = -2/3

y = -2/3x + b

Step 2: Find <em>b</em>

6 = -2/3(-12) + b

6 = 8 + b

b = -2

Step 3: Rewrite perpendicular equation

y = -2/3x - 2

Can you please explain how to do this so I can understand what to do for the other questions
tatyana61 [14]

Answer:

The circle length is 90*pi which should be 3.14

So the circle length is 282.6

The central angle is 90 degree which is 1/4 part of 360 degree

From the theory of arc, the arc length should also be 1/4 part of circle length.

So the answer should be 1/4 * 282.6 = 70.65

Becasue it should be to the nearest tenth, so the answer should be 70.7
