Answer:
Step-by-step explanation:
If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. Also, a decrease in the value of one variable would cause a corresponding decrease in the other variable.
Given that Y varies directly with X, and Y = 15 and X = 5, if we introduce a constant of proportionality, k, the expression becomes
15 = 5k
k = 15/5
k = 3
The equation would be
Y = 3X
Therefore, when X = 9, the value of Y would be
Y = 3 × 9
Y = 27
Considering the situation described in the problem, the length of segment AD is of: 17 units.
<h3>How to find the length of segment AD?</h3>
From the situation described in the problem, segment AD is divided into three parts:
Then, the length of segment AD is:
AD = AB + BC + CD.
We have that AC = 9, hence:
AB + BC = 9.
We also have that BD = 10, then:
BC + CD = 10.
Since BC = 2, we have that:
- AB + BC = 9 -> AB + 2 = 9 -> AB = 7.
- BC + CD = 10 -> 2 + CD = 10 -> CD = 8.
Then the length of segment AD is given as follows:
AD = AB + BC + CD = 7 + 2 + 8 = 17.

I think you divide 1/2 by -2/5 and then add that to -1/4....
Hi there!
To Round of the number given, first you have to find the ten thousands place on the given number. Started from ones, tens, hundreds, and moving on, the number in the ten thousands place would be 7 in your case.
Now, looking to the number on the right of 7 which is 8, it is bigger than 5, and therefore, we round up 7 and let 8 go to zero.
Applying this, your answer would be 4,280,003
Hope this helped!
