Answer:
28
Step-by-step explanation:
Question Image is attached.
Triangle BED and Triangle CFD are similar.
We can let the length of BD be 5x and DC 7x
We also know BC = 48, thus we can write:
5x + 7x = 48
12x = 48
x = 4
Now, Since DC = 7x, we plug in x = 4 into it.
DC = 7x
DC = 7(4)
DC = 28
Length of DC is 28
Answer:
-4
Step-by-step explanation:
In the formula y=mx+b the m is slope. the equation y=-4x-3 is in y=mx+b form.
from there we can deduct that -4 is the slope
