Answer:

Step-by-step explanation:

15. (-4-3)/(-5-0)= -7/-5= 7/5

y - 3 = 7/5x - 0

y = 7/5x + 3

16. (-2-3)/(4-0)= -5/4

y - 3 = -5/4x - 0

y = -5/4x + 3

17. (-3+5)/(0+3)= 2/3

y + 5 = 2/3(x + 3)

y + 5 = 2/3x + 2

y = 2/3x - 3

18. (-2-2)/(0+4)= -4/4= -1

y - 2 = -1(x + 4)

y - 2 = -x - 4

y = -x - 2

19. y - 3 = 1/2x - 0

y = 1/2x + 3

20. y - 2 = -(x + 1)

y - 2 = -x - 1

y = -x + 1

21. perp. -5/3

y + 5 = -5/3x + 0

y = -5/3x - 5

22. perp. 1/2

y + 1 = 1/2(x + 4)

y + 1 = 1/2x + 2

y = 1/2x + 1

23. perp. 3/4

y + 5 = 3/4(x + 4)

y + 5 = 3/4x + 3

y = 3/4x - 2

24. perp. 7/5

y - 4 = 7/5(x - 5)

y - 4 = 7/5x - 7

y = 7/5x - 3

34.98+12.24=? answers please

Ksivusya [100]

Answer:

Hello!

After reading your question I have calculated the correct answer to be:

47.22

Step-by-step explanation:

The way I solved this equation was I first split the equation into two parts.

I took the two whole numbers, being "34" and "12", and made their own equation:

"34+12=?"

And then I took the two partial numbers "0.98" and "0.24" and made their own equation:

"0.98+0.24=?"

I then solved both equations:

"34+12= 46"

"0.98+0.24= 1.22"

And added those two solutions together to come up with the final solution:

"46+1.22= 47.22"

Hope this helped!

10 push-ups in 2 days= ?

bekas [8.4K]

Answer:

10 pushups?

or 20 if you do 10 pushups per day.

that would be an extra 24 calories burned (12 each day), depending on how fit you are, and not nearly enough pushups to be of any help to your physical health.

I'm bad at math so uh yeahhh

____ [38]

Answer and Step-by-step explanation:

Since we know that lines l and m are parallel (we are just proving that they are parallel), we can see that the two angles given are corresponding angles, so they are congruent to each other.

123 = 2x + 7

Subtract 7 from both sides.

116 = 2x

Now, divide both sides by 2.

58 = x

So, the value of x is 58.
