The slope for -8y=2x+5 is m=-1/4

Answer:

-1/4

Step-by-step explanation:

in y=mx+b, m represents the slope. Let's try to get your equation to look like that. We can see that on the left side, the y is not yet alone so we must try to accomplish that. to do that we divide by -8 from the -8y, but we must also do that to the other side. you would get y=-2/8x-5/8. then we would simplify the -2/8x into -1/4x. Now it is y=-1/4x-5/8 and that resembles y=mx+b. m is slope and -1/4 is m.

Please answer this and thank you<br><br> If DE=4x+10, EF=2-1, and DF=9x-15, find DF.
professor190 [17]
I hope that 2-1 means 21.

DE + EF = DF
4x + 10 + 21 = 9x - 15
4x + 31 = 9x - 15
31 = 9x - 4x - 15
31 = 5x - 15
46 = 5x
x = 9 1/5 = 9.2

You want 9x - 15
9*9.2 - 15
82.8 - 15
67.8 <<<<< answer. 
If I have given the wrong meaning to 2-1 (which could mean 1) leave another note and I will correct my work.

The car treves 15 milies in 3 hours.
solong [7]

9514 1404 393

Answer:

  • 5 mph
  • 50 miles

Step-by-step explanation:

To find miles per hour, divide miles by hours:

  (15 mi)/(3 h) = 15/3 mi/h = 5 mi/h

__

To find distance, multiply speed by time.

  (5 mi/h) × (10 h) = 50 mi
