Answer:

Step-by-step explanation:
The picture of the question in the attached figure
we know that
The triangle ABD is an isosceles triangle
because
AB=BD
The segment BM is a perpendicular bisector segment AD
so
<em>In the right triangle ABM</em>
Applying the Pythagorean Theorem

we have

substitute

-----> equation A
<em>In the right triangle BMC</em>
Applying the Pythagorean Theorem

we have

substitute


----> equation B
equate equation A and equation B

solve for x

Simplify

<em>Find the length of DC</em>

Answer:
y = 5/2x - 7
Step-by-step explanation:
5x - 2y = 4
5x - 4 = 2y
y = 5/2x - 2
Slope = 5/2
Point (2,-2)
y-intercept: -2 - (5/2)(2) = -2 - 5
= -7
