If 2x/2y=16,what is the value of x-y?
kotegsom [21]

Answer:

15y

Step-by-step explanation:

first the 2 can cancel:

\frac{2x}{2y} =16

turns into:

\frac{x}{y} =16

now since we need to find x-y,

x=16y

16y-y=15y

I might come back to this because I'm not 100% sure this is the answer you are looking for. Let me know if you have any questions.

1. FIND THE EQUATION OF THE LINE THAT PASSES THROUGH THE GIVEN POINT (1,2) AND (-1,5)
alina1380 [7]

Answer:

slope: (y₂ - y₁) / (x₂ - x₁)

(5 - 2) / (-1 - 1) = 3/-2 = -3/2

y = -3/2x + b

5 = -3/2(-1) + b

5 = 3/2 + b

b = 3.5

y = -3/2x - 7/2

(5.83 - 1.42) / (4.22 + 0.72) = 4.41/4.94

y = 4.41/4.94x + b

5.83 = (4.41/4.94)(4.22) + b

5.83 = 3.76724696 + b

b = 2.06275304

y = 4.41/4.94x + 2.06

(the numbers are really wacky so i hope thats right, so sorry if it isn't)
