Answer:
∠ADB ≅ ∠CBD
Step-by-step explanation:
I did the quiz and got an hundred.
Two lines are parallel if they have the same slope. Two likes are perpendicular if they have opposite reciprocal slopes.
-3x + 7y = 5
7y = 3x +5
slope = 3/7
3y = -7x +15
Slope = -7/3
So, these lines are perpendicular.
Hope this helps!

Step-by-step explanation:
Hello
<span>the slope of the line, on the x slope-its 6, on the y slope its -2 is : (-2)/(6) = -1/3</span>
Answer:
-0.8

Solve and move the constants to opposite side. I'm going to subtract 12 from both sides.
Now solve for a by dividing both sides by 7.5
