Answer:
1) Given
2) Definition of Midpoint
4) Substitution PoE
5) 4x=16
6) Divison PoE
Step-by-step explanation:
1) is given because it is given.
2) Should be definition of midpoint because a midpoint bisects a line, meaning both sides are congruent.
4) is substitution because, like aforementioned, AC=6x and CD=2x+16, so substitute those numbers in the equation.
5) is 4x=16 because that's what happens when you subtract 6x-2x.
6) should be division PoE because to isolate x you need to divide by 4.
The equation would look like this: 14+x= 17. To find the answer, you can either subract 17-14 or add to fourteen until you get to seventeen. Your answer is 3. It's the same either way. Hope this helps.
Exponential relationships are relationships where one of the variables is an exponent. So instead of it being '2 multiplied by x', an exponential relationship might have '2 raised to the power x': Usually the first thing people do to get a grasp on what exponential relationships are like is draw a graph.
Doing so you'll get the answer
