Answer:
8
Step-by-step explanation:
[-2][-2]=-2 x-2=4
4+4=8
No. The y-intercept is the value of y when x=0, hence it intersects the y-axis when x=0. In this case:
0^2-4(0)+y^2=-3
y^2=-3
y=√-3
Since there is no real square root of a negative value, the curve does not intersect the y-axis
No matter what type of polygon<span> you have, the </span>sum<span> of the </span>exterior angles<span> is ALWAYS equal to 360°. If you are working with a regular </span>polygon<span>, you can </span>determine<span> the size of EACH </span>exterior angle<span> by simply dividing the </span>sum<span>, 360, by the number of </span>angles.
