Answer:
9
Step-by-step explanation:
Distance between two points is given as;
Square root [(X2-x1) 2+ (y2-y1)2]
= (6-(-3))2 +(-4-(-4))2
=Square root (81 +0)
=9
A is true. There is no vertical line that can intersect this graph twice.
B is false. The function is defined for all

.
C is true. The minimum value of

is

.
D is false. The piecewise function is made of one semicircle and one line, just two functions.
E is also false. The circular arc is a nonlinear function.
Thus, the answer is A and C.
3x^2-18x+24
3(x^2-6x+8)
3(x-4)(x-2)
The final price is $437.25
25%=0.25
1-0.25=0.75
550x0.75=412.5
6%=0.06
412.5x1.06=437.25$
I got 42. Don't know if it's right though.
