Answer:

y = -x+8

Step-by-step explanation:

The side that is parallel to BC is EF

Find the slope of EF:

m = \frac{2-4}{6-4} =\frac{-2}{-2} =-1

Easiest way is just put the formula in point-slope form and simplify.

Let's use point F, which is (6,2)

y -2=-(x-6)

Simplify:

y-2=-x+6

Add 2 on both sides:

y = -x+8

Hope this helped

What is 3/4 doubled? Is it 6/8 or 1 2/4?
Amanda [17]

Answer:

1 2/4

Step-by-step explanation:

3/4 doubled is 2(\frac{3}{4} )=\frac{3}{2}

Now, \frac{6}{8} =\frac{3}{4} on simplification.

1 \frac{2}{4} =\frac{6}{4} =\frac{3}{2}

Therefore,

3/4 doubled is 1 2/4
