Which equation represents a circle with the same center as
the circle shown but with a radius of 2 units?
(4-4)2 = (y – 5)² = 2
(1. - 477 + (y-5) = 4
(4-5)2 + (y – 4)2 = 2
1.-55% + (y-4)2 = 4

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

m∠a is 90°

m∠b is 40°

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
