Answer:

"If the line has a slope that is not 0, then the the line is not horizontal".

Step-by-step explanation:

The contrapositive of "If p then q" is "If not q then not p".

p=a line is horizontal

not p= a line that is not horizontal

q=the line has a slope equal to zero

not q=the line has a slope that is not zero

The equivalent statement in contrapositive form is therefore:

"If the line has a slope that is not 0, then the the line is not horizontal".

A horse ran 800 m in 40 seconds 1200 m in 60 seconds in 480 m and 24 seconds is this a proportional relationship if so what is t
Naddik [55]

Answer:

Yes this is a proportional relationship.

Equation is;

D=20T

Step-by-step explanation:

A horse run;

800m in 40 seconds

1200m in 60 seconds

and

480m inn 24 seconds

800m ÷ 40s = 1200m ÷ 60s = 480m ÷ 24s = 20

The equation here is Distance(D) = 20 × Time(T)

D=20T

It implies that the distance of the horse is directly proportional to the time it takes to run.

20.36

21.-87

22.0

23.-10

24.9>4

25.8>-8

26.7>-3

27.-3,5,4,-6

28.1,8,-7,-5

Step-by-step explanation:

For example in the 'lines' |27| it represents the number. if it were let's say |-7| to "simplify" it would make it 7. if it were |7| it would be 7. and if it was let's say -|7| it is -7 because you do |7| but the negative is in front of it still causing it to be negative. if it were -|-7| you'd do what's in the lines/parentheses so it would be - 7 so you'd have to move the negative in front of the 7 to make it negative so your answer is -7
