Answer:
contrapositive
Step-by-step explanation:
The <u>converse</u> statement would be ...
b ⇒ a
The <u>contrapositive</u> swaps the parts and negates them both:
¬b ⇒ ¬a . . . . . matches your given statement
The <u>inverse</u> negates both parts:
¬a ⇒ ¬b
A <u>contradiction</u> arises when the implication is false: a is true and b is false.
It will take 26.1 minutes because 5.22x5 is equal to 26.1
Answer:
-2
Step-by-step explanation:
The midpoint is the average of the end point coordinates, so ...
4 = (y +10)/2 . . . . the y-coordinate is the average of the y-coordinates
8 = y +10 . . . . . . . multiply by 2
-2 = y . . . . . . . . . . subtract 10
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.
