Points (x,y) on the circle satisfy x^2+y^2=100.

Points inside the circle satisfy x^2+y^2.

Points outside the circle satisfy x^2+y^2>100.

We have

2^2+8^2=4+64=68

so the point (2, 8) lies inside the circle.

Line 2x-4y-7=0 meets the x axis at point (k,0). Find the value of k
kolbaska11 [484]
K=4
add seven on both sides
2x-4y=7
add 4y on both sides
2x=7+4y
divide 2 on both sides
x=7+4y/2
plug that into original equation
2(7+4y/2)-4y-7=0
7 and 4y cancel out
2(2)=0
4=0
