Alright so, let’s break this down.
To find the first coordinate you need to solve the first equation
To do that you can do
6+9=15
So that mean 3x has to be equal to 15
You divide 15 by 3
The answer to that is the solution to the first equation, or the first coordinate.
For the second one, you know x has to be negative because the solution is negative
2x is going to have to equal -20
-20/2 gets you the solution
Remember that it will be negative
You now have both of the coordinates
You take coordinate A and technically add coordinate B to it
You do that because B is negative and A is positive
Then you have the answer to c
An inequality is solved by more than one value - usually an interval, or a union of intervals.
In this case, we have:

Add 14 to both sides:

Divide both sides by 12:

Answer:
The extremes are 5 and 64.
The middle terms are 80 and 4.
Step-by-step explanation:
Given the proportion:
5 : 80 :: 4 :64
To find:
The extreme and middle terms of the given proportion.
Solution:
The given statement is in proportion if and only if the product of extremes i.e. the numbers at both the ends is equal to the product of middle numbers.
OR
First number
Fourth number = Second number
Third number
First of all, let us check the two products.
5
64 = 320
And the second product:
80
4 = 320
The product is same therefore, the given numbers are in proportion.
The extreme terms are the first and the fourth numbers.
i.e. The extremes are 5 and 64.
The middle terms are 80 and 4.
-6/3, or simplified would be -2
