They're alike because they each have 5 sides. They're different because figure A has no right angles but figure B does.
Question 4 is (1,2)
Question 5 is (1,0)
These are are definitely correct
Since the triangle is isosceles the measure of angle B is also 47.
since you have dropped a perpendicular bisector the measure of angle x is 90. and since the angles must add to 180 you get 47+47+a=180 and a= 86. since y is half this we have y is 43

Answer:
C
Step-by-step explanation:
The vertex form of the equation of a circle is 
where (h,k) is the center of the circle and r is the radius. This means that for the circle with center (-3,1) and radius 5 substitute into the vertex form these values. Substitute h = -3, k= 1, and r = 5. The equation becomes 
. This simplifies to 
. The solution is C.
The range of the function y = x2 is all real numbers, y, such that y ≥ 0.
