Ggeasy

we can eliminate the y terms by adding the equations

x-y=11
<u>2x+y=19 +</u>
3x+0y=30

3x=30
divide by 3
x=10

subb ack
x-y=11
10-y=11
minus 10 both sides
-y=1
times -1
y=-1

(x,y)

Can someone explain major and minor arcs in relation to circles.
Lelechka [254]
A Major Arc within a circle is something that that is more than half of the circle, and therefore, larger than the minor arc. The way in which this could be used in an example is; Tony has a pizza with 8 slices, 6 of these slices are pepperoni and 2 are chilli beef. In this case, the pepperoni slices are the major arc and the chilli beef slices are the minor arc.
The Major Arc will always be bigger than the minor arc- whether this is 181 degrees to 179, or whether this is 350 degrees to 10 degrees.
The Minor Arc is always the smallest arc, and this can be explained by; Benedict has an apple pie that has 10 slices, between him and his friends, they have eaten four slices. In this case, they have eaten the 'minor arc'
There is a picture attached, and this is the examples of a major and a minor arc.
Hope this has been able to help you :)
