2y=-6x+8
First, the slope of any equation, is always the coefficient with the variable "x".
So, the slope for this line, is -6x.
To get rid of the coefficient with y, we need to divide 2, from both sides of the equal sign.
<u>2y=-6x+8</u>
2
y=-3+4
Now that we have our new equation, we can see that the slope of our line has also changed, from -6x to-3x. Because -6÷2=-3.
And to find the perpendicular slope, you change the reciprocal of the slope so from -3 to 1/-3 and then you change the sign of the slope so from 1/-3 to 1/3. That is your final answer.
The answer is 2) 1/3.
The only number all of these numbers can be divided by is 2. Therefore, the GCF is 2
Answer:
153
Step-by-step explanation:
An arc of length 30 m : l = 30 m.
r = 15 m, ∠ A = ?
Formula for the length of an arc is:
l = r π A / 180° ( where A is the central angle )
A = l · 180 / r π = ( 30 · 180 ) / ( 15 · 3.1415926 ) = 114.43 °
This is very close to your result.
